1 John 2:23-24

2:23 Everyone who denies the Son does not have the Father either. The person who confesses the Son has the Father also.

2:24 As for you, what you have heard from the beginning must remain in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.

1 John 4:10

4:10 In this is love: not that we have loved God, but that he loved us and sent his Son to be the atoning sacrifice for our sins.
