Prayer
Psalms 66:18 If I regard wickedness in my heart, The Lord will not hear.
James 4:2 You lust and do not have; so you commit murder. You are envious and cannot obtain; so you fight and quarrel. You do not have because you do not ask.
James 4:3 You ask and do not receive, because you ask with wrong motives, so that you may spend it on your pleasures.
