According to His excellent greatness

As I was teaching my children Psalm 150 today, this phrase struck me: "praise him according to his excellent greatness.(v.2)"

How excellent is God? "For thou, LORD, art high above all the earth: thou art exalted far above all gods.(Psalm 97:9)"

How great is God? "O Lord GOD, you have only begun to show your servant your greatness and your mighty hand. For what god is there in heaven or on earth who can do such works and mighty acts as yours? (Deuteronomy 3:24, ESV)"

There is no measure for either. "Great is the LORD and most worthy of praise;his greatness no one can fathom.(Psalm 145:3, NIV)"

There is only one response:"I will bless the LORD at all times; his praise shall continually be in my mouth.(Psalm 34:1)."
