Uh... I don’t think that Saul is relevant here, because we were talking about him as *king*, not status of salvation.
Chosen by God
Anointed by God
Given the Holy Spirit by God
Made into another man by God
Given another heart by God
Rejected later by God for disobeying commandments
Then Samuel took a vial of oil, and poured it upon his head, and kissed him, and said, Is it not because the Lord hath anointed thee to be captain over his inheritance? When thou art departed from me to day, then thou shalt find two men by Rachel's sepulchre in the border of Benjamin at Zelzah; and they will say unto thee, The asses which thou wentest to seek are found: and, lo, thy father hath left the care of the asses, and sorroweth for you, saying, What shall I do for my son? Then shalt thou go on forward from thence, and thou shalt come to the plain of Tabor, and there shall meet thee three men going up to God to Bethel, one carrying three kids, and another carrying three loaves of bread, and another carrying a bottle of wine: And they will salute thee, and give thee two loaves of bread; which thou shalt receive of their hands. After that thou shalt come to the hill of God, where is the garrison of the Philistines: and it shall come to pass, when thou art come thither to the city, that thou shalt meet a company of prophets coming down from the high place with a psaltery, and a tabret, and a pipe, and a harp, before them; and they shall prophesy: And the Spirit of the Lord will come upon thee, and thou shalt prophesy with them, and shalt be turned into another man. And let it be, when these signs are come unto thee, that thou do as occasion serve thee; for God is with thee. And thou shalt go down before me to Gilgal; and, behold, I will come down unto thee, to offer burnt offerings, and to sacrifice sacrifices of peace offerings: seven days shalt thou tarry, till I come to thee, and shew thee what thou shalt do. And it was so, that when he had turned his back to go from Samuel, God gave him another heart: and all those signs came to pass that day. And when they came thither to the hill, behold, a company of prophets met him; and the Spirit of God came upon him, and he prophesied among them.

Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the Spirit of the LORD came upon David from that day forward. So Samuel rose up, and went to Ramah. But the Spirit of the LORD departed from Saul, and an evil spirit from the LORD troubled him.

And Samuel said to Saul, Why hast thou disquieted me, to bring me up? And Saul answered, I am sore distressed; for the Philistines make war against me, and God is departed from me, and answereth me no more, neither by prophets, nor by dreams: therefore I have called thee, that thou mayest make known unto me what I shall do. Then said Samuel, Wherefore then dost thou ask of me, seeing the LORD is departed from thee, and is become thine enemy?
