#1) Always show respect to God’s chosen. David was chased by Saul and his life was almost taken many times, but David would not kill King Saul, because that was God’s chosen. He knew there would be consequences if he acted without God’s approval.
#2) You have never sinned too much to earn forgiveness from God. David was God’s chosen man, but he was also a murderer and an adulterer and let’s face it, sometimes he just didn’t get everything right, but God chose to forgive him when David asked. The same is true for us, if we will just ask God; He will forgive us of our sins. We have never gone too far to receive forgiveness.
#3) When facing the giants in your life know that God is always with you. David could not believe that no one would fight Goliath. David’s trust was in God. His words can be found in 1 Sam 17:45-47: 45 Then David said to the Philistine, “You come to me with a sword, with a spear, and with a javelin. But I come to you in the name of the LORD of hosts, the God of the armies of Israel, whom you have defied. 46 This day the LORD will deliver you into my hand, and I will strike you and take your head from you. And this day I will give the carcasses of the camp of the Philistines to the birds of the air and the wild beasts of the earth, that all the earth may know that there is a God in Israel. 47 Then all this assembly shall know that the LORD does not save with sword and spear; for the battle is the LORD’s, and He will give you into our hands.” David won that battle that day because he knew God could take care of all of his problems.
#4) You may feel like a nobody, but God can still use you. On the day David was anointed to be King, he was out tending sheep. This is not a job we would think of a future leader of Israel to have to do. God doesn’t just call us because we think we are something. He calls us because He knows He can use us. David had a tender heart to God and God used him mightily.
