God does not leave us comfortless. He always comes with words of hope and mercy. His goal in allowing hurt is not to break us but to teach us to draw close to Him in times of heartache and extreme pressure. David was the anointed king of Israel, but he was left to hide out in caves rather than serve in palaces. You may think this seems unreasonable and that God should have done something sooner to relieve his stress.
Trial is a masterful teacher.
The Lord knew his servant was in need of intensive training for the job he was called to do. It was in the desperate times that David learned how to cry out to God for mercy and help. He had to face helplessness head on and realize his only help was in the Lord God. Ziklag was a turning point for David. It was here that God ended David's running and rushing.
