The prophet Samuel had told him, The Spirit of the L ord will come upon you, and you will prophesy with the prophets and be turned into another man. Samuel s words gave Saul confidence. God would make up what was lacking. Saul was given another heart, anointing, and several signs of confirmation. As time progressed Saul lost his humble spirit.
Familiarity sometimes breeds contempt.
When Saul became prosperous, important, and accomplished, he became proud, self-confident, careless, disrespectful, and disobedient. He overstepped his boundaries and offered sacrifices as a priest. This displayed disrespect for God s order and authority. Saul was not a man not after God s heart. The Lord had said that he would establish Saul s kingdom forever, but his own heart had disqualified him from the fulfillment of the promise.
