Jesus told us that we “ought always to pray and not lose heart”.(Luke 18:1) Scientific studies have been done on prayer – with two control groups, etc. etc. It did show that the group prayed for did measurably better than the other. But then Jesus has been telling us that all the time. How dull and slow we are to learn! Our God does hear and care. He does respond. There is nothing we cannot take before Him. He desires and is working for our best good. Do pray, and not lose heart.
