But they soon forgot what he had done and did not wait for his plan to unfold

 Psalm 106:1-48

Praise the Lord! Give thanks to the Lord, for he is good; his love endures forever. Who can proclaim the mighty acts of the Lord or fully declare his praise? Blessed are those who act justly, who always do what is right. Remember me, Lord, when you show favor to your people, come to my aid when you save them, that I may enjoy the prosperity of your chosen ones, that I may share in the joy of your nation and join your inheritance in giving praise.

We have sinned, even as our ancestors did; we have done wrong and acted wickedly.
7 When our ancestors were in Egypt, they gave no thought to your miracles; they did not remember your many kindnesses.

But they soon forgot what he had done and did not wait for his plan to unfold.

Then they despised the pleasant land; they did not believe his promise. They grumbled in their tents and did not obey the Lord. ....

Save us, Lord our God, and gather us from the nations, that we may give thanks to your holy name and glory in your praise. Praise be to the Lord, the God of Israel, from everlasting to everlasting. Let all the people say, “Amen!”

Why?

God is good, but many people always forgot what he had done and did not wait for his plan to unfold.

God's plan and his way higher than us, higher than our minds. We see what we saw from our eyes, but we can't see what the Lord sees. We are limited in our flesh eyes and limited in our time.

Psalmist pray to the Lord remember me, when you show favor to your people, come to my aid when you save them. What I have and enjoy the prosperity of your chosen ones, that I may share in the joy of your nation and join your inheritance in giving praise.

Let me don't be selfish people, but generous to all, for this prosperity are the gift of the Lord with God's love and favor.

How?

Praise the Lord! Give thanks to the Lord. For his love endures forever!
