I wonder how many of us could honestly say, “Praising God characterizes my life”? The extent to which we cannot say that reflects the extent to which we are not God-centered. We’re not to be praise-centered, but God-centered. A God-centered person will be a person of praise. As God’s people, we should be focused on Him in every situation, and therefore we should be people of praise.
Psalm 150 gives us the where, why, how, and who of praise. It does not give us, per se, the what of praise. Just so we’re clear at the outset, when we’re talking about praising God we are not talking about repeating “Praise the Lord” over and over. We are talking about thinking and/or speaking well of God’s perfect attributes or great acts. Praise can be expressed through singing and music (including clapping, dancing, lifting our hands, kneeling, lying prostrate, etc.), through testimony and thanksgiving, prayer, sacrificial service, and giving.
Praise to God comes naturally when you count your blessings. No matter how bad you have been through, praise His Name. All things work together for good for those who loves Him and are called according to His purpose. He deserves all the praise and adoration that comes from us.
