Originally, God had anointed Saul to become king…but slowly over time Saul abused his power in corrupt & improper practices. So much so that here Samuel is comparing Saul’s disobedience to soothsaying & pagan idol worship. Jesus summed this up in Mark 12:33 when He replied to the Jewish leaders that loving God and others was more important than all burnt offerings and sacrifices. For when we reject God and His Word in defiance & insubordination, and think we know more than Him, we move away from God in sin.
