2 Samuel 1:8
"And he said unto me, Who art thou? And I answered him, I am an Amalekite."
The last act of Saul's life is a sad one. He was in a battle with the Philistines when one soldier drew his bow, shot at Saul and hit him. Saul fled from the battle wounded, but the Philistines pursued hard after him. As he saw them coming and knowing what they would do to him if they captured him, he asked a young man who was behind him who he was. He responded, "I am an Amalekite." Saul asked the Amalekite to slay him for he did not want to be abused by the Philistines.
Hold on! It was an Amalekite who slew Saul. In the final minutes of Saul's life the one thing that caused God to pull His blessings from him was that he did not destroy the Amalekites. God told Saul, "Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass." (1 Samuel 15:3) Yet, we find a few verses later that the Scriptures say, "But Saul and the people spared Agag, and the best of the sheep, and of the oxen, and of the fatlings, and the lambs, and all that was good, and would not utterly destroy them: but every thing that was vile and refuse, that they destroyed utterly." (1 Samuel 15:9) Saul's incomplete obedience came back to get him several years later. It was his incomplete obedience that marked the final act of his life when an Amalekite killed him.
Sin always has a way of coming back to get us if we don't take care of it. Incomplete obedience is still disobedience. The one thing God always demands from every Christian is complete obedience. God says, "Behold, to obey is better than sacrifice, and to hearken than the fat of rams." (1 Samuel 15:22) You may obey God in everything but one area, and that is still disobedience.
Moreover, what you consider unimportant in God's commands are considered important by God. It is not your business to decide what is right and wrong, but it is your responsibility to obey all that God commands you to do. If God felt something was unimportant, then He would not have commanded you to do it.
Furthermore, in whatever area you disobeyed God, it will eventually come back to get you. God says in Numbers 32:23, "...and be sure your sin will find you out." Saul's disobedience in this area didn't really hurt him for many years, but it finally hurt him and marked the final act of his life. He will forever be remembered as being slain by the Amalekite. You may feel that you have gotten away with your sin, but it will come back and get you if you don't confess it to God and take care of it.
What is your Amalekite? What is it that you have done that you feel you have gotten away with? Friend, sin that is not dealt with is like a seed of cancer that one day will flourish and ravish your life. Don't let the sin which you did not deal with be the final act of your life. God is a wonderful God Who will forgive and cleanse you from your sin if you will simply confess it to Him. I beg you to come clean right now. Don't let all that you worked for in your life be destroyed at the final act of your life. Sin will surely do that if you don't take care of it.
