1 John 5:13-21 - Our Assurance Of Eternal Life
13 these things have I written to you, that you may know that you have eternal life, by your believing on the name of the son of God.
14 Besides, we have this confidence in him, that if we ask any thing according to his will, he will hear us. 15 and since we are sure that he hears all our prayers, we are sure that the petitions we presented to him, will be answered.
16 If any man see his brother commit a sin, which is not a mortal sin, let him pray to God, who will grant him life, for such as do not commit a mortal sin. there is a sin unto death: in which case I do not enjoin any prayer to be made. 17 every thing that is contrary to virtue, is a sin: but every sin is not a mortal sin:
18 we know that a true christian will not commit such a sin, for he that is the child of God keeps upon his guard, so that the wicked spirit does not approach him.
19 we know that we are the children of God, and the rest of the world are subject to the evil spirit.
20 We know that the son of God is come, and hath given us an understanding to know him that is true: and we are with him that is true, by his son Jesus Christ. "he is the true God, who is the author of eternal life."
21 dear children, keep yourselves from idols. AMEN.
