The Lord our God is holy

Psalm 99:1-9
The Lord reigns, let the nations tremble; he sits enthroned between the cherubim, let the earth shake.  Great is the Lord in Zion; he is exalted over all the nations.  Let them praise your great and awesome name— he is holy.  The King is mighty, he loves justice— you have established equity; Exalt the Lord our God and worship at his footstool;
he is holy. Moses and Aaron were among his priests,
Samuel was among those who called on his name; they called on the Lord and he answered them.
He spoke to them from the pillar of cloud; they kept his statutes and the decrees he gave them.
Lord our God, you answered them; you were to Israel a forgiving God, though you punished their misdeeds.
Exalt the Lord our God and worship at his holy mountain,
for the Lord our God is holy.
Why?
God is holy almighty and have mercy.
Forgiving and punishment both exist. God discipline us with love and troubles.
Lord is holy so we shoud fear the Lord and trust in Him.
How?
Confess my sins,my proud eyes,dirty mouth,selfishness, criticism etc.
