"Let every thing that hath breath praise the Lord. Praise ye the Lord."
Psalm 150:6
We are created to praise the Lord. And, by the way, don't just think of praising Him in the congregation. Praise Him in your own private prayer time and throughout your day.
Learn to maintain an attitude of praise and thanksgiving. When praise becomes natural to in your own private life, it won't be difficult to praise Him in the midst of the congregation.
Are you longing for a revival of God's presence in your life? Are you tired of just hearing about the glorious manifestations of His power in the past? Then open your mouth and your heart and do what God has created you to do. Praise!
