David’s faith in God had been strong, but it had failed him when he placed himself under the protection of the Philistines. He had taken this step without seeking the counsel of the Lord; but when he had sought and obtained the favor of the Philistines, it was poor policy to repay their kindness by deception. In the favor they had shown him they had been actuated by selfishness. They had reason to remember the son of Jesse, for his valor had cost them their champion, Goliath, and had turned the tide of the battle against them. The Philistines were glad of an opportunity to separate David’s forces from the army under Saul. They hoped that David would avenge his wrongs by joining them in battle against Saul and Israel (The Signs of the Times, November 16, 1888).

 This demonstrates the fact that great and good men, men with whom God has worked, will make grievous mistakes when they cease to watch and pray, and to fully trust in God.
 There is a precious experience, an experience more precious than fine gold, to be gained by everyone who will walk by faith. He who will walk in the way of unwavering trust in God will have a connection with heaven. The child of God is to do his work, looking to God alone for strength and guidance. He must toil on without despondency and full of hope, even though he is placed in most trying and aggravating circumstances.
 David’s experiences are recorded for the instruction of the people of God in these last days. In his warfare against Satan, this servant of God had received light and direction from heaven, but, because the conflict was long continued, and because the question of his receiving the throne was unsettled, he became weary and discouraged (The Signs of the Times, November 9, 1888).
