"Howbeit for this cause I (Paul) obtained mercy, THAT IN ME FIRST Jesus Christ might shew forth all longsuffering, FOR A PATTERN TO THEM WHICH SHOULD HEREAFTER BELIEVE ON HIM to life everlasting." 1 Tim. 1:16.
Hereafter believe: "But Now". You want to live your life as a workman for God who does not need to be ashamed when you stand before Him? Paul is your pattern to follow. Paul was a chosen vessel to Jesus Christ. And he tells you every revelation that Christ gave him for us in this age of grace.
So. As I read your post, you believe Jesus’s ministry is relevant to us in so far as He says to follow St. Paul.
Because: “Paul is your pattern to follow.”
It sounds like a fun little puzzle your teachers made of the New Testament and likely quite interesting to scramble and fit the pieces together in novel ways.
However, did it ever occur to you somewhere along the way that being a follower of Christ, a Christian, would be incongruent with the statement: “Paul is your pattern to follow.”?
