Call to Worship (Psalm 100)

The Lord commands people to worship him.  Why does God need his creatures to worship him?  He is a God who is complete in himself so why does he give such a command?  What do we know about God that makes it a joy to worship Him?  Why will His people want to worship Him?

Cross Examination (Malachi 1:6-14)

The Lord has established for Israel that the Lord really does love Israel.  The Lord is also one who has been faithful to the promises of the covenant of grace.  The Lord has delivered, defended, and deposited Israel right where they need to be.  Now the Lord turns to cross examine Israel.  Have they loved the Lord as they should?  How has Israel failed to love the Lord?
