1 Samuel 28:17-18 The Lord has done what he predicted through me. The Lord has torn the kingdom out of your hands and given it to one of your neighbors—to David. Because you did not obey the Lord or carry out his fierce wrath against the Amalekites, the Lord has done this to you today. 
When we do not obey the Lord, there are consequences. Sometimes, God will use others to fulfill His purpose in our place, causing us to lose an honored position previously granted by the Lord.

1 Samuel 27:10-11 When Achish asked, “Where did you go raiding today?” David would say, “Against the Negev of Judah” or “Against the Negev of Jerahmeel” or “Against the Negev of the Kenites.” He did not leave a man or woman alive to be brought to Gath, for he thought, “They might inform on us and say, ‘This is what David did.’” And such was his practice as long as he lived in Philistine territory. 
David hurt others on purpose to protect himself long before his encounter with Bathsheeba. Even the “man after God’s own heart” had his downfalls. Lord, thank You for loving me I spite of myself.

Luke 12:31 But seek his kingdom, and these things will be given to you as well.
God will provide all I need as I seek Him and His kingdom first. 

1 Samuel 26:25 Then Saul said to David, “May you be blessed, David my son; you will do great things and surely triumph.”So David went on his way, and Saul returned home. 
When we do what the Lord asks of us by showing love to our enemies, they will no longer pursue us.

Luke 12:29 And do not set your heart on what you will eat or drink; do not worry about it.
Is my heart “set” on earthly issues or trusting Christ for heavenly issues?

1 Samuel 25:39 When David heard that Nabal was dead, he said, “Praise be to the Lord, who has upheld my cause against Nabal for treating me with contempt. He has kept his servant from doing wrong and has brought Nabal’s wrongdoing down on his own head.” Then David sent word to Abigail, asking her to become his wife. 
May I let the Lord deal with those who do me harm.

Luke 12:25 Who of you by worrying can add a single hour to your life ?
Jesus recognizes the futility of worrying. Do I?

1 Samuel 24:3-6 He came to the sheep pens along the way; a cave was there, and Saul went in to relieve himself. David and his men were far back in the cave. The men said, “This is the day the Lord spoke of when he said to you, ‘I will give your enemy into your hands for you to deal with as you wish.’” Then David crept up unnoticed and cut off a corner of Saul’s robe. Afterward, David was conscience-stricken for having cut off a corner of his robe. He said to his men, “The Lord forbid that I should do such a thing to my master, the Lord’s anointed, or lay my hand on him; for he is the anointed of the Lord.” 
The Lord gives us choices when dealing with our personal enemies. We can do them harm or grant them mercy. Which one would I choose for my enemies?

1 Samuel 23:1-4 When David was told, “Look, the Philistines are fighting against Keilah and are looting the threshing floors,” he inquired of the Lord, saying, “Shall I go and attack these Philistines?” The Lord answered him, “Go, attack the Philistines and save Keilah.” But David’s men said to him, “Here in Judah we are afraid. How much more, then, if we go to Keilah against the Philistine forces!” Once again David inquired of the Lord, and the Lord answered him, “Go down to Keilah, for I am going to give the Philistines into your hand.” 
How often does my fear or the fear of others make me question the Lord’s direction? Lord, give me strong faith.

Luke 12:21-22 “This is how it will be with whoever stores up things for themselves but is not rich toward God.” Then Jesus said to his disciples: “Therefore I tell you, do not worry about your life, what you will eat; or about your body, what you will wear.”
Vs. 21 is connected to vs. 22. If I don’t value my spiritual riches I will default to worry.
