If you believe in the deity of Christ, can you explain 1 Timothy 2:4-5?

The Apostle Paul wrote that the truth is that there is one God and one mediator between God and men, a man Christ Jesus.

The apostle differentiated between God and Jesus the Christ. Christ Jesus is not God, but a man.

If the Apostle Paul thought that Jesus had to be God or a God-man to atone for our sin, or to be our mediator, why would the apostle write that the one mediator between God and man is a man?

This verse, and many others like it, is a clear statement that for the Apostle Paul, a man (not a God-man), Jesus the Messiah, was the true and sufficient mediator between God and man.
