After King Jehoshaphat led Judah in prayer beseeching God for His help in their time of need, they stood before the Lord. (Background of story in 2 Chronicles 20) We must have an attitude of expectancy when we pray and after we pray. Most times when people have prayed, they have moved on immediately.
There is no “standing before the Lord” anticipating a response. God must become so real to us that we treat Him as though He hears us personally. Then He has a response to us personally. We may not hear or see an immediate response but we should not assume there is none.
There should be a pause after we pray to allow God to respond. If we practice doing that it will help God to become more real to us and it will also produce more answered prayer.
