Keep his precepts and observe his laws

Psalm 105:26-45
The Lord chose Moses his servant and Aaron to perform his miraculous signs among them in Egypt.
Egypt was glad when they left because dread of Israel had fallen on them.
For the Lord remembered his holy promise given to his servant Abraham. He brought out his people with rejoicing, his chosen ones with shouts of joy; he gave them the lands of the nations, and they fell heir to what others had toiled for - that they might keep his precepts and observe his laws.
Why?
This is the covenant God who protect and saves. 'Praise the Lord!'
The Lord brought his people out from Egypt with rejoicing, and Egyptian are glad they go for the dread of Israel had fallen on them, the Lord did ten miraculous sings - ten disasters.
The Lord is faithfulness, He has mighty hands, He is covenant God. All of these works are let his people keep his precept and observe his laws. But how weakness a man, 1000 years Israelite rebelled his laws. Jesus came to earth to be our savior, turn our heart to Jesus, believe him His only son - Jesus Christ, we will get the eternal life and erase all of our sins. This is the most miraculous sings in this generation.
How
Keep his precepts and observe his laws for the Lord is my King, my fortress, my savior.
