1 Samuel 27:1
"Now I shall perish one day by the hand of Saul.  There is nothing better for me than that I should escape to the land of the Philistines."

What could have happened to David?  How did he become so convinced of Saul killing him that he went to Achish again for protection? 

Remember the first time, in 1 Samuel 21:10-15, when David sought protection from Saul by going to Achish, the king of Gath.  David became so concerned that Achish might take his life, he started acting insane by scratching on doors and drooling down his beard.  But here he is again allowing his dread, anxiety, and fear of Saul to cause him to turn to Achish once more. 

David going to Achish is a drastic reversal of David's faith in the LORD's ability to protect him and make him the king of Israel.  Over the last few chapters, God has shown His strong arm of protection not only to David but others.  Saul himself acknowledged God protection of David.  In 1 Samuel 24:20 Saul said, "I know that you shall surely be king, and that the kingdom of Israel shall be established in your hand."  Abigail recognized God's activity in David's life.  In 1 Samuel 25:28-29 she says, "For the LORD will certainly make my lord a sure house...the life of my lord shall be bound in the bundle of the living in the care of the LORD your God."  Even Abishai was willing to go with David to the center of Saul's camp because he understood God's care of David.  But for some reason, David could not see the LORD's hand at this time.  

Don't you know David was tired of running, even with the encouragement of those around him?  Could it be because his family, the Ziphites, from the tribe of Judah, had recently given him up to Saul?  Did his lack of faith in man affect his trust in God?   

Has that ever happened to you?  Have friends and relatives seen God's action in your life when you were blind to the fact?  When I finally acknowledged the call of God on my life to fulfill the role of pastor, a surprising number of people made comments such as "What took you so long?  It has been obvious for a long time this was where God was directing you." 

Paul understood the likelihood of believers struggling just as David did.  Five times Paul says "do not lose heart" or "let us not grow weary."  The Greek word Paul used is enkakeo which means "to cease wrongly." 

When Paul says "Brothers, do not grow weary in doing good" (2 Thessalonians 3:13) or, "I ask you not to lose heart over what I am suffering" (Ephesians 3:13), he is encouraging them not to stop trusting God because it would be wrong.  It seems that David grew weary and lost heart even though those around him knew God was doing what He promised. 

LORD God, who knows the secrets of the heart.  Thank You for allowing us to see David struggle, even though he was a man after Your own heart.  We know even when we lose heart or grow weary, You never do.  We are aware You never need to rouse Yourself.  You are the Watchman who never sleeps.  Holy Spirit, when the circumstances of life cause us to lose heart, please surround us with Your encouragement and fellow believers who see Your activity and encourage us to see it as well.
