What will it take from God to make you praise Him and rejoice in Him, that He has not already done. (and by the way, our praise and rejoicing should be first in WHO HE IS, and moreover what he has done); 

faulty barriers follow:
Before you rejoice and praise God, It will take that God, either:
1. Save a sinner. (see external fruit in evangelism).
2. Mature the sheep. (see external fruit in discipleship).
3. Purge the goats. (see external fruit in discipline.)
4. Help you financially or occupationally? 
5. Enlarge your congregation. (repeat #1).

How foolish am I to murmur against God or impose on God some task of my own petty mind; Nay, dear self, God is already worthy of your fullest praise and rejoicing because of who he his and because of that Scripture testifies to His work, grace, and glory.
