What Hinders Our Prayers

Asking wrongly. You ask and do not receive, because you ask wrongly, to spend it on your passions. James 4:3

Doubting. But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind. For that person must not suppose that he will receive anything from the Lord. James 1:7-8

Regarding iniquity. If I regard iniquity in my heart, the Lord will not hear me: But verily God hath heard me; he hath attended to the voice of my prayer. Blessed be God, which hath not turned away my prayer, nor his mercy from me. Psalm 66:18-20 (KJV)
