1 John 3 - Matthew Henry's Concise Commentary on the Bible

The satisfaction the believer has about Christ, and eternal life through him.

Little does the world know of the happiness of the real followers of Christ. Little does the world think that these poor, humble, despised ones, are favourites of God, and will dwell in heaven. Let the followers of Christ be content with hard fare here, since they are in a land of strangers, where their Lord was so badly treated before them. The sons of God must walk by faith, and live by hope. They may well wait in faith, hope, and earnest desire, for the revelation of the Lord

Jesus. The sons of God will be known, and be made manifest by likeness to their Head. They shall be transformed into the same image, by their view of him. (1Jn 3:3-10)
