1 John 5:15 WEB

¹³  These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.

¹⁴  This is the boldness which we have toward him, that, if we ask anything according to his will, he listens to us.

¹⁵  And if we know that he listens to us, whatever we ask, we know that we have the petitions which we have asked of him.

¹⁶  If anyone sees his brother sinning a sin not leading to death, he shall ask, and God will give him life for those who sin not leading to death. There is a sin leading to death. I don't say that he should make a request concerning this.

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