Then Moses entreated the Lord his God, . . . . . So the Lord changed His mind about the harm which He said He would do to His people.
Exodus 32:11‭-14 NASB

God hears the prayers of His righteous ones. He answers them according to His will. He is near the one who calls upon Him in truth. He will fulfill the desire of the those who fear Him; He will also hear their cry and will save them. The righteous cry, and the Lord hears and delivers them out of their troubles.
1 John 5:14/Psalm 145:18-19/Psalm 34:17 NASB

Then why are we not earnestly praying?

We know that God does not hear sinners; but if anyone is God-fearing and does His will, He hears him.
John 9:31 NASB
And if we know that He hears us in whatever we ask, we know that we have the requests which we have asked from Him.
1 John 5:15 NASB

🌹And all things you ask in prayer, believing, you will receive.”
Matthew 21:22 NASB

Continually Seeking Him,
