1 John 3:14; 1 John 5:16; 1 John 5:17

1 John 3:14

14 We know that we have passed out of death into life, because we love the brethren. He who does not love abides in death.

1 John 5:16

16 If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this.

1 John 5:17

17 All unrighteousness is sin, and there is a sin not leading to death.
