Wesley's Notes for 1 John 2:1

2:1 My beloved children - So the apostle frequently addresses the whole body of Christians. It is a term of tenderness and endearment, used by our Lord himself to his disciples, #John 13:33|. And perhaps many to whom St. John now wrote were converted by his ministry. It is a different word from that which is translated little children, in several parts of the epistle, to distinguish it from which, it is here rendered beloved children. I write these things to you, that ye may not sin - Thus he guards them beforehand against abusing the doctrine of reconciliation. All the words, institutions, and judgments of God are levelled against sin, either that it may not be committed, or that it may be abolished. But if any one sin - Let him not lie in sin, despairing of help. We have an advocate - We have for our advocate, not a mean person, but him of whom it was said, This is my beloved son. Not a guilty person, who stands in need of pardon for himself; but Jesus Christ the righteous; not a mere petitioner, who relies purely upon liberality, but one that has merited, fully merited, whatever he asks.

The Unction of the Holy Spirit. Antichrist. The Anointing Which Teacheth All Things. My little children. From so aged a teacher as John, now probably more than four score, and at least fifty years in the service of Christ, this fatherly style of address is very appropriate. That ye sin not. He writes to exhort them to a pure and holy life, the only life permissible to those born again. And if any man sin. The word "man" is not found in the Greek. The meaning is, "If any brother, any of you, should be overtaken by sin", there is a way of forgiveness. They must not sin, but if unhappily one does sin, let him go to Christ, the Advocate. We have an advocate with the Father. Who pleads with the Father not to withdraw his love because we may have been betrayed into sin.
