I had a question regarding the divinity claims regarding Jesus Christ and the essence of our human sin condition being solved through Jesus. If Jesus did not claim to be God, then it would appear His death on the cross was in vain, so how can we be truly freed from this sin condition and find favor with God? Why even bother saying, “It is finished”? 

God percieves sin as an action that has eternal consequences. For centuries, many major world religions have had people do certain finite actions to find favor to please a infinite God. I see no point in doing these actions (such as facing a certain way when praying, giving money to certain institutions, confessing sins to a priest, doing good works to counteract bad ones, traveling to specific holy places) to please God when we can never attain His favor by our own merit alone.  

However, I see Jesus coming in human flesh as a perfect being, dying on the cross as God, as one that is only able to solve a sin problem that has eternal consequences because Jesus is an eternal solution being that He was sent by God.

Therefore stating:

One Eternal God + Eternal Sin Problem = Need For An Eternal Solution

Jesus Dying on Cross as The Eternal Sacrifice + Eternal Sin Problem = Eternal Solution Through Belief Alone In Him

Therefore the intial concern of solving an eternal sin problem is solved by faith alone in Jesus Christ and not through a finite human being’s good works. If we could attain favor with God through works alone, everyone could easily put on an obnoxious display of good works to find more favor than the other person. However, to this extreme, how geninue is one’s faith. At that point, it just seems to me to become a competition.
