Psalms 66:16-20 (KJV) Come and hear, all ye that fear God, and I will declare what he hath done for my soul.
I cried unto him with my mouth, and he was extolled with my tongue.
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.

When God will not hear prayer

If we regardless in quint u in our hearts if we cling to any known sin, the Lord will not hear us; but the prayer of penitent, contrite soul is always accepted. When all knownworng are righted. We may be live that God will answer our petitions. Our mermit will never commend us to the favor of God; it is the worthless of Jesus will save us, His blood will cleanse us, yet we have a work to doing con plying with the condition of acceptance.
