Adam Clarke on 1 John 4:7

Beloved, let us love one another - And ever be ready to promote each other's welfare, both spiritual and temporal.

For love is of God - And ever acts like him; he loves man, and daily loads him with his benefits. He that loveth most has most of God in him; and he that loveth God and his neighbor, as before described and commanded, is born of God, εκ του Θεου γεγεννηται, is begotten of God - is a true child of his heavenly Father, for he is made a partaker of the Divine nature; and this his love to God and man proves.
