1 John 5:13-21 - Our Assurance Of Eternal Life
13 These things have I written to you, who believe on the name of the son of God, that ye may know that ye have eternal life, and that ye may the more firmly believe on the name of the Son of God.
14 And this is the confidence, which we have towards Him, that if we ask any thing according to his will, He heareth us: 15 and if we know that He heareth us in whatsoever we ask; we know that we shall have the petitions, which we have requested of Him.
16 If any one see his brother commit a sin which is not unto death, let him pray for him, and God will give him life, that is for them that do not sin unto death. There is a sin unto death: and for that I do not say that he should pray. 17 All unrighteousness indeed is sin, and yet there is a sin not unto death.
18 We know that whosoever is born of God, doth not practise sin: but keepeth himself from it, and the wicked one doth not touch him.
19 We know that we are of God, and the whole world lieth under the wicked one.
20 But we know that the son of God is come, and hath given us understanding, that we may know Him that is true, and we are in Him that is true, and in his son Jesus Christ: He is the true God, and eternal life.
21 Little children, keep yourselves from idols. Amen.
