Jesus promised. Abide in Him, He in you and you in His Word, ask anything within His name, with faith, in His name, within God's will, and nothing will be impossible for you. God answers His children's prayers because they do what pleases Him. The righteous individuals prayer is powerful and effective. The sinners prayer is weak for God answers the prayers of the one who worships Him and does His will. Turn your hearing from the law and your prayer becomes an abomination. If you cherish sin in your heart your prayers will be ignored. With all this in mind, all members of the body of Christ, the children of God, all and I mean all, are followed by signs, wonders and miracles. So, if you're going to a church with no power I suggest you find the presence of God in the right church..
