What does 1 John 2:1-2 mean?

¹ My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: ² And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world. (1 John 2:1-2 KJV)

Christ Our Advocate

Here the apostle encourages believers against sins of weakness (1 John 2:1-2), shows the true knowledge and love of God (1 John 2:3-6), renews the command of brotherly love (1 John 2:7-11), addresses various stages of Christian growth (1 John 2:12-14), warns against love for the world (1 John 2:15-17) and against deceivers (1 John 2:18-19), shows the security of true Christians (1 John 2:20-27), and advises them to remain in Christ (1 John 2:28-29).

These verses continue the subject from the previous chapter, where the apostle proceeds on the understanding that even real Christians still sin. Here he gives both a warning and a comfort.

1. Warning. He gives no encouragement to sin:
   “My little children, I am writing you these things so that you may not sin” (1 John 2:1). The purpose of this letter, and of what was just said about fellowship with God and how it is broken by a sinful life, is to turn you away from sin.

Notice the affectionate way he addresses them: “My little children”—perhaps because they were converted through his message, or because they were younger in faith and experience, and certainly because they were dear to him in the gospel. The gospel spreads most where ministerial love abounds. Some may understand the apostle to mean, “I write this not so that you sin,” which ties the verse back to the assurance of pardon in 1 John 1:9—”God is faithful and just to forgive us our sins.” The statement prevents abuse of such grace.

Though sins are forgiven to those who repent and confess, the apostle writes not to encourage sin but to remind them of their remedy. “But if anyone does sin, we have an advocate with the Father” (1 John 2:1). This statement anticipates the possible misunderstanding that forgiveness encourages sin and corrects it by pointing to Christ as the solution, not the excuse.

2. The believer’s comfort in the case of sin: “But if anyone does sin, we have an advocate with the Father—Jesus Christ the righteous” (1 John 2:1). Believers—even those who are secure in the blessings of the gospel—still sin. There is, however, a difference between those in Christ and those outside Him. Among sinners, there are those who are converted and those who are not. Even though believers sin, they have access to an advocate in heaven to maintain their standing and bring them continued forgiveness.

This is the comfort and refuge of true Christians: “We have an advocate.” The term used here is sometimes given to the Holy Spirit, translated as “Comforter.” The Holy Spirit acts within us, guiding and teaching us to pray and repent. But this advocate is not within us—He is in heaven, with the Father. The advocate’s role is to plead with the Judge. Our Judge, in this case, is our Father—formerly our Judge in the legal sense but now our Father in the gospel, seated on a throne of mercy. “You have come… to God, the Judge of all” (Hebrews 12:23). To encourage us even further, the advocate is described in specific terms:

1. By His person and name: Jesus Christ, the Son of the Father—anointed for the full work of salvation, including intercession.
2. By His qualification: He is “the righteous one.” In this court, the advocate must be righteous, not the client. Other advocates can be unrighteous themselves and still defend a just cause. But here, since the clients (sinners) are guilty, they need an advocate who is righteous on their behalf. Christ’s own righteousness is what He pleads, so that our sins may not be counted against us.
3. By His basis of appeal: “He is the atoning sacrifice for our sins” (1 John 2:2). He offered Himself as the sacrifice to satisfy divine justice. It is false to distinguish between an advocate of redemption and one of intercession. The one who intercedes for us is also the one who died for us. It is His sacrifice that He presents in heaven, showing that His blood is still of value. “He always lives to intercede for those who come to God through Him.”
4. By the scope of His work: “And not only for ours, but also for the sins of the whole world” (1 John 2:2). His atonement is not limited to one nation or people. It is not only for Jews or early believers, but for all who believe in every nation and age. Christ is the only and universal sacrifice for all who are brought to God and to His grace and forgiveness.
