Saul was rejected because he didn’t really see himself as God’s anointed. If he had, he would have obeyed God, not man.
Jesus is the Christ, the Messiah, the Anointed. He had God’s Spirit without measure. He was the fulfillment of the Law and the Prophets. He reigns.
But, his reign came at a price. The cross. Can you imagine a King that submits to death? Can you imagine a King that literally rises from the dead to reign? Well, most of the Jew couldn’t. That’s why they rejected him. But, God didn’t. Jesus put his faith in his Father who had the power to literally raise him from the dead.
Well, we now have God’s Spirit (Acts 2, I Corinthians 6). We will reign with Christ (II Timothy 2:11-13; Revelation 5:9-10; Revelation 20:6). We will judge angels (I Corinthians 6:3). We are a kingdom of priests (Revelation 5:9-10). We have duties, responsibilities, and blessings. I say that to say, like Saul, we have to believe that. We have to believe that God will never leave nor forsake us. In that way, we can carry out our responsibility, and we can say with Peter,
“We must obey God rather than men,” Acts 5:29.
And, we can say with the Hebrew writer,
“The Lord is my helper; I will not be afraid. What can mere mortals do to me,” Hebrews 13:6.
If Saul had had that attitude, he would have reigned.
If you have that attitude, you will.
