Every kind of prayer, not intercessory prayer only, which is the highest kind of prayer, but all prayer, from the lowest kind to the highest, is impossible in a life of known and allowed sin.
Alexander WhyteYou do not really care for God's mercy or His comfort either, so long as you live in any sin. And it is well that you do not; for you can have neither. Your peace will be like a river, when you put away your sin; but not one word of true peace, not one drop of true comfort, can you have till then.
Alexander Whyte
