This type of attitude will help us to receive reproof, correction and rebuke so that we can yield the peaceable fruits of righteousness. Back to praise and worship, God's focus is on the state of the heart. People lift their hands. People sing songs. People play instruments.
People shout, scream and dance.
After all the dust of these happenings occur, the focus is still the same. The last question is the focal point of where this is going today. Therefore, the purest essence of praise and worship comes from the heart. I'm thoroughly convinced that this concept is such a cliche today that we really miss the truth of this aspect sometimes. God desires that we love Him with all our mind, all our strength and all of our heart.
