13 I write this to you who believe in (adhere to, trust in, and rely on) the name of the Son of God [in 1 the peculiar services and blessings conferred by Him on men], so that you may know [with settled and absolute knowledge] that you [already] have life, 2 yes, eternal life. 14 And this is the confidence (the assurance, the privilege of boldness) which we have in Him: [we are sure] that if we ask anything (make any request) according to His will (in agreement with His own plan), He listens to and hears us. 15 And if (since) we [positively] know that He listens to us in whatever we ask, we also know [with settled and absolute knowledge] that we have [granted us as our present possessions] the requests made of Him.
16 If anyone sees his brother [believer] committing a sin that does not [lead to] death (the extinguishing of life), he will pray and [God] will give him life [yes, He will grant life to all those whose sin is not one leading to death]. There is a sin [that leads] to death; I do not say that one should pray for that. 17 All wrongdoing is sin, and there is sin which does not [involve] death [that may be repented of and forgiven].
18 We know [absolutely] that anyone born of God does not [deliberately and knowingly] practice committing sin, but the One Who was begotten of God carefully watches over and protects him [Christ's divine presence within him preserves him against the evil], and the wicked one does not lay hold (get a grip) on him or touch [him].
19 We know [positively] that we are of God, and the whole world [around us] is under the power of the evil one.
20 And we [have seen and] know [positively] that the Son of God has [actually] come to this world and has given us understanding and insight [progressively] to perceive (recognize) and come to know better and more clearly Him Who is true; and we are in Him Who is true--in His Son Jesus Christ (the Messiah). This [Man] is the true God and Life eternal. 21 Little children, keep yourselves from idols (false gods)--[from anything and everything that would occupy the place in your heart due to God, from any sort of substitute for Him that would take first place in your life]. Amen (so let it be).
