And Samuel said to Saul, “The LORD sent me to anoint you king over his people Israel; now therefore listen to the words of the LORD. Thus says the LORD of hosts, ‘I have noted what Amalek did to Israel in opposing them on the way when they came up out of Egypt. Now go and strike Amalek and devote to destruction all that they have. Do not spare them, but kill both man and woman, child and infant, ox and sheep, camel and donkey.’”
So Saul summoned the people and numbered them in Telaim, two hundred thousand men on foot, and ten thousand men of Judah. And Saul came to the city of Amalek and lay in wait in the valley. Then Saul said to the Kenites, “Go, depart; go down from among the Amalekites, lest I destroy you with them. For you showed kindness to all the people of Israel when they came up out of Egypt.” So the Kenites departed from among the Amalekites. And Saul defeated the Amalekites from Havilah as far as Shur, which is east of Egypt. And he took Agag the king of the Amalekites alive and devoted to destruction all the people with the edge of the sword. But Saul and the people spared Agag and the best of the sheep and of the oxen and of the fattened calves and the lambs, and all that was good, and would not utterly destroy them. All that was despised and worthless they devoted to destruction.
The word of the LORD came to Samuel: “I regret that I have made Saul king, for he has turned back from following me and has not performed my commandments.” And Samuel was angry, and he cried to the LORD all night.

Selective obedience is the same as disobedience. God gave clear instructions to Saul to utterly destroy the Amalekites, sparing nothing. Saul chose instead to do things his way, and as a result paid the consequences for his actions. He was rejected by God. How many times have we taken situations into our own hands, doing what we please, knowing that we are going against God’s will? God has our best interest at heart, so whatever He tells us to do, let us do it knowing that it will be for our good, no matter how it seems at that particular moment.'
