Praise and worship

Psalm 66:1-20
How awesome are your deeds! How awesome his works in man's behalf!
Come and see what God has done; come, let us rejoice in him.
You tested us; you refined us like silver. But you brought us to a place of abundance.
Come and listen, all you who fear God; let me tell you what he has done for me.
If I had cherished sin in my heart, the Lord would not have listened.
Praise be to God, who has not rejected my prayer or withheld his love from me.
When prayer is answered and troubles are past, the heart overflows with praise.
Praise to God who has always come to his people's rescue, from the earliest days .
Thanksgiving, and an offering of thanks, for God's love and care for every individual.
Why?
Praise how awesome God is, he did on us, on his people.
Come and see God's works and come to rejoice in him.
Even God has burden on out backs, but God bring us to a place of abundance, so the test and the burden is good to us, let us know more about God and give thinks to Him.
The procedure is difficulty and pain when God refined us like silver, but after tested our life will be improved, more like God.
God listen my prayer, if I had sin in my heart, God won't listen. So psalmist has not like wicked but like come to the Lord, so his prayer were listened by God.
How?
Praise be to the Lord. who has not rejected my prayer.
