God is love

This is a metaphor which means "the character of God is love." See how you translated this in 1 John 4:8. (See: rc://en/ta/man/translate/figs-metaphor)

the one who remains in this love

"those who continue to love others"

remains in God, and God remains in him

To remain in someone means to continue to have fellowship with him. See how you translated "remains in God" in 1 John 2:5-6. Alternate translation: "continues to have fellowship with God, and God continues to have fellowship with him" or "stays joined with God, and God stays joined with him" (See: rc://en/ta/man/translate/figs-metaphor)
