1-е Иоанна 3:16

What true love to the brethren is, illustrated by the love of Christ to us. Hereby--Greek, "Herein." the love of God--The words "of God" are not in the original. Translate, "We arrive at the knowledge of love"; we apprehend what true love is. he--Christ. and we--on our part, if absolutely needed for the glory of God, the good of the Church, or the salvation of a brother. lives--Christ alone laid down His one life for us all; we ought to lay down our lives severally for the lives of the brethren; if not actually, at least virtually, by giving our time, care, labors, prayers, substance: Non nobis, sed omnibus. Our life ought not to be dearer to us than God's own Son was to Him. The apostles and martyrs acted on this principle.

The apostle here magnifies the love of God in our adoption (Jo1 3:1, Jo1 3:2). He thereupon argues for holiness (Jo1 3:3), and against sin (v. 4-19). He presses brotherly love (Jo1 3:11-18). How to assure our hearts before God (Jo1 3:19-22). The precept of faith (Jo1 3:23). And the good of obedience (Jo1 3:24).

3:16-18 Christ’s example shows that real love involves self-sacrifice. We do this by becoming truly concerned about the needs of others and by unselfishly giving time, effort, prayer, possessions, and even our lives to supply those needs.
