This was the case with many of the kings of Israel, including the first one. Saul started out with humility, but he gradually came to consider his position as something that belonged to him. He forgot that he had a special assignment from God to lead His chosen people in a way that would show other nations the way to God. When God relieved him of duty, Saul’s only concern was for himself (1 Sam. 15:30).
In a world where ambition often compels people to do whatever it takes to rise to positions of power over others, God calls His people to a new way of living. We are to do nothing out of selfish ambition (Phil. 2:3) and to lay aside the weight of sin that ensnares us (Heb. 12:1).
If you want to be someone who truly “rises up,” make it your ambition to humbly love and serve God with all your heart, soul, mind, and strength (Mark 12:30).
Ambition is short-sighted if our focus is not on God. (RBC)
