Whoever confesses that Jesus is the Son of God

"Those who say the truth about Jesus, that he is the Son of God." (UDB)

God remains in him, and he in God

See how this was translated in 1 John 2:4.

God is love

This is a metaphor which means "The character of God is love." (See: rc://en/ta/man/translate/figs-metaphor)

and he who remains in love remains in God, and God remains in him

This can be translated “those who continue to love others have a close relationship with God, and God has a close relationship with them.”)
