To understand this Psalm better, remember it is like the Lord as a Man speaking to God.
V.2-3 The Lord Himself, finds His delight in those whom He calls His saints. It specially refers to those who will trust in Him and wait for Him in a future day. He loves His saints! All believers are known as saints or holy ones.
V.5-8 The perfectly dependent Lord Jesus is described in these verses. He turns to the Lord His God, and trusts Him for everything and thanks Him for His faithfulness.
V.10 This refers to the then future resurrection of the Lord Jesus from the dead.
V.11 What happy confidence! The Lord Jesus prophetically looks forward to the joy, after His death and resurrection, of being at the right hand of God in glory. That is where He is now.
