And you are confusing the election OF SPECIFIC INDIVIDUALS for ministry and service with the election of sinners for salvation. Huge difference.
You could include Moses, Elijah, David, and Solomon, etc. (including all the apostles) in that pantheon. Throughout the history of Israel, God chose (elected) certain men for certain tasks. You see this in the book of Judges. Gideon did not believe that he should be a deliverer in Israel, but God chose him for that job. Christ chose Peter as the apostle to the Jews (even after he denied the Lord thrice) and then He chose Paul as the apostle to the Gentiles, even though he murdered Christians.
But none of this has a bearing on salvation. Since salvation is offered to all, God cannot possibly choose some for salvation. That is why He requires OBEDIENCE TO THE GOSPEL. So you need to learn about this matter.
