Is to be worshipped?
Forgive sins of humanity?
Serve as an example?
Of course many would say all three but I'm asking for you to choose the main function or role..
Because depending on the church it seems one of these will be emphasized over the other..
You're going to hear what you didn't want to, but the comprehensive answer is the right answer. All three of those roles are connected, and thus it is no surprise you will see them emphasized at different times. Jesus' role begins with the forgiveness of sins, but the forgiveness of sins is accomplished only for those who accept the salvation and Lordship of Christ. If one has
sincerely accepted Christ (which will be determined by the claim matching the life, i.e., if Jesus is
actually your Lord you will
actually obey Him, Luke 6:46) then they have received the Holy Spirit, and the Holy Spirit will bring us to worship God because He is the same Spirit who filled Christ in His humanity: "The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry,
“Abba, Father (Romans 8:15)."
Since worship is to give all our heart, soul, strength and mind to God (Matthew 22:36-38), it is impossible to worship God and not have our actions, thoughts and attitudes reflect it. Since we ought to live a certain way, Christ, who was perfectly obedient,
is an example to us as to how we are to live in every way. This is why the Scripture says: "We know that we have come to know him if we keep his commands. Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person. But if anyone obeys his word, love for God is truly made complete in them. This is how we know we are in him: Whoever claims to live in him must live as Jesus did (1 John 2:3-6)."
So the roles are inextricably connected; you can not have one without the other. Therefore the only way in which any of them is primary is the order in which they are effectuated.
Great.
You didn't answer my question(s).
So Jesus is out to save me from myself?
What does that even mean?
What would I do to myself if Jesus doesn't save me from myself?
Jesus would be saving you from self-inflicted condemnation, the worst kind of self-harm. By choosing to live separately from the very source of all life, truth, goodness, joy and all provision you will receive the conscious existence of the absence of all such things, which is an incommensurate threat to your existence. You could attempt to retort that it is not self-inflicted because by some definition you didn't choose to be damned, but you would have chosen a path that inevitably ends at that destination. You have freedom of choice, not freedom from consequence. Just as the criminal is responsible when they live unlawfully and are jailed, and the lazy glutton is responsible when their body prematurely fails because they abandoned healthy living, so the godless will receive a result that corresponds to their desires.
Since God is the Creator and provider of every thing that constitutes the knowable, the good, the pleasant, and every good thing you've ever enjoyed (everything He provides from food to social satisfaction to sexual intimacy and everything between), the removal of God from your conscious being entails the removal of all those things. To expect the contrary would put you in the awkward position of being like a woman who asks a man she finds physically attractive and wealthy to remain present with her exclusively so that she can look upon upon him and spend his wealth at leisure, but demands that he otherwise behave as though soulless and never demand relationship or returned love. No man with any dignity would ever accept such a thing, and God, being infinitely more worthy so as to be worthy of worship, will not accept it either.
To put it as plainly as the Scripture does, give yourself to God to honour Him and enjoy Him forever, or go where neither He nor anything He has provided is present, as you requested in every waking moment of the rejection your life constitutes. As has been said, there is no good and pleasant thing you've ever enjoyed that wasn't from God's mind. If this world can have such pleasantries as God has provided in this finite existence, it can not even be imagined, nor has any eye seen or ear heard what God has prepared for those who love Him (1 Corinthians 2:9).
