Fasting works by humbling the flesh and the independently-minded soul of man. The Bible reveals that God is moved by fasting, if done with a right heart attitude. Even wicked king Ahab in the Old Testament moved God one time when he fasted. Prayer really works. God is pleased when we invest time in prayer, drawing near to Him in humility and believing that something will happen because we pray.
