No man hath seen God] I propound not God simply to be imitated in all things, because he is invisible, John 1:18. 1 Timothy 1:17. Exodus 33:10. but in his love to us, which hath been so fully manifested. Or, ye may more easily love your brother, whom ye can see, then God, whom ye cannot see; as vers. 20. if we love one another] As we know we have a soul in us, by the working of it, though we see it not: so we know that God is in us, if his Spirit hath wrought love in us to his children. his love is perfected in us] Chap. 2. 5. He makes us sure that he loves us. Or, he makes us love him more fully. Or, to know that our love to him is true, v. 17. Or, our love to him is more fully manifested, 2 Corinthians 12:9. James 2:22.
