“And it was so, that when he had turned his back to go from Samuel, God gave him another heart” (1 Samuel 10:9). King Saul was a different person after his encounter with Samuel. God not only changed his outward appearance when he turned him into another man (1 Samuel 10:6), but the inner man was transformed also.
“The heart includes not only the motives, feelings, affections, and desires, but also the will, the aims, the principles, the thoughts, and the intellect of man. In fact, it embraces the whole inner man” (3820). After God turned Saul into another man, people that knew Saul before would have said, you’ve changed, you seem different to me. After God give him another heart, Saul would have said, I’ve changed, I am different person than I was before. Saul underwent a complete transformation before he became king of Israel.
The inner spiritual and moral transformation that Saul experienced resulted in a single-minded commitment to the LORD and his will. It is comparable to the change described in Ezekiel 36:26 where it was prophesied ” A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you a heart of flesh.”
Saul was God’s chosen instrument to establish his kingdom in the Promised Land. In the same way that the Israelites were his chosen people, on an individual level, Saul was God’s chosen man to be king of his people. God’s choosing or election is a part of the process that results in Christians being born again. Saul is an example of God performing the process even before Christ was born.
The interesting thing about Saul’s experience is that he had no say in the matter. God did not ask Saul if he wanted to be king nor did he do it because Saul deserved to be king. Saul’s transformation was necessary so that he could function effectively as king. God made Saul into a king because the Israelites wanted a king and Saul was the man God selected.
