It is the will of God to grant eternal life to those who have not abandoned apostolic Christianity.
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.
17 All unrighteousness is sin, and there is a sin not leading to death.
New American Standard Bible: 1995 Update(La Habra, CA: The Lockman Foundation, 1995), 1 Jn 5:16–17.
