EXPOSITION
When the lame man was healed, he kept on jumping, running, and praising God. He publicly demonstrated what he felt inwardly. Many times, you keep quiet about the good things Jesus Christ does for you; doing that is an act of ingratitude.
Talk about the goodness of the Lord publicly. Doing this is also an act of sharing the gospel with others. Praise God in both good and bad times. Praise God for your answered and unanswered prayers.
LESSON LEARNT: Praise the Lord, for it is also an act of preaching.
