[Note: This is part 4 in a six-part series looking at the First Epistle of John. Some of the material is adapted from my commentary That You May Know: The First Letter of John. During this series, we won’t necessarily touch on every single verse, but will look at the major messages that 1 John presents.]
See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him. Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is. And everyone who thus hopes in him purifies himself as he is pure.
Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness. You know that he appeared in order to take away sins, and in him there is no sin. No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him. Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous. Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil. No one born of God makes a practice of sinning, for God’s seed abides in him; and he cannot keep on sinning, because he has been born of God. By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.
For this is the message that you have heard from the beginning, that we should love one another. We should not be like Cain, who was of the evil one and murdered his brother. And why did he murder him? Because his own deeds were evil and his brother’s righteous. Do not be surprised, brothers, that the world hates you. We know that we have passed out of death into life, because we love the brothers. Whoever does not love abides in death. Everyone who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.
By this we know love, that he laid down his life for us, and we ought to lay down our lives for the brothers. But if anyone has the world’s goods and sees his brother in need, yet closes his heart against him, how does God’s love abide in him? Little children, let us not love in word or talk but in deed and in truth.
By this we shall know that we are of the truth and reassure our heart before him; for whenever our heart condemns us, God is greater than our heart, and he knows everything. Beloved, if our heart does not condemn us, we have confidence before God; and whatever we ask we receive from him, because we keep his commandments and do what pleases him. And this is his commandment, that we believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. Whoever keeps his commandments abides in God, and God in him. And by this we know that he abides in us, by the Spirit whom he has given us (1 John 3:1-24).
Today, we continue our study of 1 John. After pausing briefly to discuss the characteristics of an “anti-Christ” (“Antichrists Among Us: 1 John 2:18-29”), John now turns back to the marks or evidences of a follower of Christ. How can we know that we are saved and in Christ? In addition to being theological in nature, this section has strong practical implications and teachings. (Which is, after all, the goal of good theology—to change us and our behavior to align us with God’s Word.) It also takes us on a journey, from grace and hope to confidence and assurance before God. Read in its entirety, it’s a great encouragement to continue in the faith.
Grace and hope lead to purity (vv. 1-3).
John’s opening words in chapter 3 are meant to evoke a response of “Wow!” And, in truth, once a believer truly understands what has been done for him, that reaction is quite natural. The guilty are forgiven, but that’s not all. They are called righteous in God’s sight, but that’s not all. The ones who were once guilty and alienated from God are called children of God! And if that weren’t enough, we are promised, as children of God, that one day we shall be like Him, once again morally perfect without any spot or blemish.
Some things that stand out here:
- Not only are we “called” (declared) children of God, but “so we are” (v. 1). There’s a difference between simply being declared a child of God (in a judicial sense) and actually “being one” (in the sense of nature or identity). We are children of God. We are Beloved of the Father.
- Because we are in fact children of God, we are no longer children of the world. Thus, John says, the world does not know us (v. 2). In the same way, the world did (and does) not know Christ.
- The end goal is not to just be with Christ. It is to be like Him. And John encourages us to remember that it will happen. It is a certain hope, not simply wishful thinking. And “everyone who thus hopes in him purifies himself as he is pure” (v. 3). It is that very hope that enables and encourages us to live pure.
Purity means practicing righteousness (vv. 4-10).
To be pure, according to John, is to practice righteousness (v. 7). As we have said many times over, John refers to “the practice of” righteousness, rather than any single act (the same way he looks at sin). A broken clock shows the correct time sometimes. But a working clock does so consistently. In the same way, a believer will consistently, if not perfectly, practice righteousness. The unbeliever, however, is like the broken clock. He cannot help but live a life of sin. John reminds us that the one who practices sin also practices lawlessness. This is because the unbeliever is living as a law unto himself, rather than doing the will of God.
The implication of this, then, is that one who claims to know God yet has not changed from a life of habitual sin has never encountered or known Him, John says. And one who has truly encountered Christ and abides in him cannot help but change from a life of sin to one of righteousness (v. 6). The change may–indeed will–be progressive, but it will absolutely take place, because one who has God’s seed in him cannot help it (v. 9). The practice of righteousness, then, is one of the surest marks of a believer (v. 10).
Practicing righteousness includes loving the brethren (vv. 11-18).
The message that John is reminding his readers is the same one he taught them “from the beginning” (v. 11). The message is that we should love one another. He then gives a pointed contrast. We should not be like Cain, who killed his brother Abel. Why did Cain kill Abel, John asks? He gives two answers. First, because Cain was “of the evil one” (v. 12). Cain had no fear of or faith in God. How do we know this? Because of John’s second reason: “Because [Cain’s] deeds were evil and his brother’s righteous” (v. 12b). The Lord confirmed this position when He told Cain, “If you do well, will you not be accepted” (Gen. 4:7). The implication is that Cain’s offering was unacceptable to the Lord, and the context suggests that it was because of Cain’s attitude. Therefore, John says, just as Cain hated his brother (hatred being the seed of murder), we should not be surprised that the world hates us.
When we can say we love the brothers (here John seems to focus on the household of faith), “we have passed out of death into life” (v. 14). For, whomever hates his brother walks in darkness. (This is the same conclusion that he gave in 2:9-11 when he mentions loving the brothers.) Further, the one who hates his brother “is a murderer,” John concludes (again, hatred being the seed of murder). This is clearly equivalent to Jesus’ teaching on murder (Matt. 5:21-22).
John concludes this statement with a blunt observation: “And you know that no murderer has eternal life abiding in him” (v. 15). How are we to take this statement? Does it suggest that murder is an unforgivable sin? For various reasons, that cannot be the case. John’s point here, as in many other places, is simply that one who continues to allow hatred to dwell in his heart is not a true believer. We are not talking about a single act, but rather the attitude of the heart. The Gospel, according to John, sets one free from hatred.
One might then ask John, “What does loving my brother look like?” His answer is very practical: “By this we know love, that he laid down his life for us, and we ought to lay down our lives for the brothers. But if anyone has the world’s goods and sees his brother in need, yet closes his heart against him, how does God’s love abide in him” (vv. 16-17). Love of the brothers consists of generous giving. We place others above ourselves. James would wholeheartedly agree with these statements (see James 1:27; 2:15-16). Love is practical and active. Otherwise it is useless. As John puts it, “Let us love in deed and truth, not just word or talk” (v.18).
Practicing righteousness leads to assurance before God (3:19-24).
A believer who truly practices righteousness and loves the brethren can find assurance before God, John writes. He first addresses an anxious question, that of the one whose heart condemns them (vv. 19-20). We can be assured in two ways: First, if we know that we are practicing righteousness and love toward the brethren as best we know, then we can be assured that we are in Christ. Second, even if our heart should condemn us, God is greater than our heart and knows everything (including our heart).
Can a believer’s heart condemn him? Most certainly. Whether it be from an immature conscience, unrealized sin, or simply the ever-present attacks by the enemies of Christ, it is not uncommon for true believers to experience guilt, doubt and anxiety. This is why John gives this encouragement.
The apostle then turns to the rest–those that have clean hearts that do not condemn them. To these he says that they can have “confidence” before God. This distinction is not by accident. The one who is condemned by their heart, though they are truly saved, can hardly have true confidence in the midst of anxiety, guilt and doubt. But when one is in a place of having a clean heart, then such a person can truly step out with the boldness of Christ to do His will, asking what he will and receiving his requests (vv. 21-22). Such a person, John says can have that confidence because he keeps Christ’s commandments.
It’s important to point out that there is no well-defined progression from one who needs assurance to the one who has confidence before God. It is possible (and common) for a believer to be in one state at one time in his life, move to the other state, and then back to the first. This is often the result of spiritual growing pains.
Finally, John summarizes what he has told us so far: The commandment is that we believe in Jesus Christ and love one another (v. 23). And he promises that those who keep those commandments do truly abide in God and God in them (v. 24a). As a final reminder, John tells us that we can know for certain that we are God’s, by the fact that He has given His Spirit to abide in us (v. 24b).
