The little verse of Psalm 66:18  teaches us a whole lot about God – and prayer.  Just in this tiny verse we see:  “If I regard wickedness in my heart, The Lord will not hear.” I am born again, and God has forgiven me of all my sins. However, on any given day or moment, if I come to Him in prayer AND am holding a sin, so to speak, or allowing a sin to have a place in my life — then, the Bible tells me: God will not give heed to what I say.
