Joh 16:23-27 "In that day you will not question Me about anything. Truly, truly, I say to you, if you ask the Father for anything in My name, He will give it to you. "Until now you have asked for nothing in My name; ask and you will receive, so that your joy may be made full. "These things I have spoken to you in figurative language; an hour is coming when I will no longer speak to you in figurative language, but will tell you plainly of the Father. "In that day you will ask in My name, and I do not say to you that I will request of the Father on your behalf; for the Father Himself loves you, because you have loved Me and have believed that I came forth from the Father."

1Jo 5:14-15 This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us. (15) And if we know that He hears us in whatever we ask, we know that we have the requests which we have asked from Him.

1Jo 5:16-17 If anyone sees his brother commit a sin that does not lead to death, he should pray and God will give him life. I refer to those whose sin does not lead to death.

(venial vs. moral sin - from catholic doctrine). Others believe like Ananias and Sophira - sudden death from sin. Others, consider this blasphemy against Holy Spirit Mat 12: Mark 3. A. Begg: "bitter hardened resistance to the truth of God revealed in Jesus, a recalcitrance to the truth. it's not the magnitude of the sin that prevents its pardon, it is rather the attitude and disposition of the sinner. For the sinner refuses to find cleansing and forgiveness in the only solution that is offered (1 John 1:9)"
