Integrity of heart and skilled hands

Psalm 78:55-72
After Israelite entered the promised land,they put God to test and rebelled the Most High; Like their fathers they disloyal and faithless, as unreliable as a faulty bow.- after two generations of Joshua death
The Lord angered with their high places and idols. He rejected Israel completely. He abandoned the tabernacle of Shiloh and sent his ark of this might into captivity. He gave his people over to the sword. -At time of priest Eli.
Then the Lord awoke as from sleep, as a man wakes from the stupor of wine. he beat back his enemies; he put them to everlasting shames.- Enemies are Philistines....
Then he rejected the tents of Joseph, he did not choose the tribe of Ephraim; but he chose the tribe of Judah.
He chose David his servant and took him from the sheep pens; from tending the sheep he brought him to be the shepherd of his people Jacob of Israel his inheritance.
David shepherded them with integrity of heart; with skilled hands he led them.
Why?
The psalmist thinks over the reasons for Ephraim's rejection, and finds them in Israel's history.
The Lord awoke as from sleep, He had mercy to the Israelite even He was angered with them, he heard the cry of his people, so the Lord strengthened his hands to rescued them.
Then is the timing, the Lord control the time.
The Lord abandoned the tabernacles and ark, those are the symbol when the heart of men apart away the Lord, all these symbol loss it's meaning. Like cross is a symbol, it is meaningless to a unbeliever of God. But it is precious to a real Christian, it is the blood of Jesus shed for us.
To be a king to shepherd his people with integrity of heart and skilled hand from the Lord. Most of the president in this world control their people with his greed and wicked minds.
How?
Mercy is the Lord who never forsake his people forever, He help the righteous people in right time.
Pray to the Lord give me gift of integrity of heart and skilled hands to serve God in this world.
