And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
Ver. 23. And this is his commandment] This is the sum and substance of the gospel, that we believe and love; and the more we believe God's love to us, the more love shall we bear one to another; for our love is but a reflex of his.
And love one another, as he gave us commandment] Lo, love is a commandment; we should therefore not only submit, but embrace it joyfully as a gift.
