While Christ was alive (as a man) He lived a perfect sinless life showing us there is a way that pleases God. Throughout His teachings He urged us to do the will of God. And one of the aspects of doing the well of God is to be righteous, and we are made righteous through the blood of Christ. But to say the power of Christ is only in His life, and forget about the power of His death and resurrection, is interesting.
He died because He was the perfect lamb, without His blood (without Him dying on that cross) then we could not be saved in the manner of which we are saved now. Without His resurrection, then He did not defeat death.
We are told that when we take the Lord's Supper, we proclaim His death. "For as often as you eat this bread and drink this cup you proclaim the Lord's death til He comes." 1 Corinthians 11:26
Paul tells us in 1 Corinthians 15:12-28
12 Now if Christ is preached that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, then Christ is not risen. 14 And if Christ is not risen, then our preaching is empty and your faith is also empty. 15 Yes, and we are found false witnesses of God, because we have testified of God that He raised up Christ, whom He did not raise upif in fact the dead do not rise. 16 For if the dead do not rise, then Christ is not risen. 17 And if Christ is not risen, your faith is futile; you are still in your sins! 18 Then also those who have fallen asleep in Christ have perished. 19 If in this life only we have hope in Christ, we are of all men the most pitiable.
The Last Enemy Destroyed
20 But now Christ is risen from the dead, and has become the firstfruits of those who have fallen asleep. 21 For since by man came death, by Man also came the resurrection of the dead. 22 For as in Adam all die, even so in Christ all shall be made alive. 23 But each one in his own order: Christ the firstfruits, afterward those who are Christs at His coming. 24 Then comes the end, when He delivers the kingdom to God the Father, when He puts an end to all rule and all authority and power. 25 For He must reign till He has put all enemies under His feet. 26 The last enemy that will be destroyed is death. 27 For He has put all things under His feet. But when He says all things are put under Him, it is evident that He who put all things under Him is excepted. 28 Now when all things are made subject to Him, then the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.
Before I end this post, I want to make it clear that I do not assume in anyway that you think:
1.) Christ's death is not meaningful or powerful
2.) That He did not rise for the dead
What I am arguing against is the idea that the power of Christ is in His life ONLY. He lived a sinless life, that is powerful, but the reason for Him to come to earth and die was so that He can reconcile God and man and that was through His death. He rose again and is our mediator. Now, this is how I sum it up for myself: The power of Christ is that He lived sinless, He died perfect and He rose victorious.
Understood, though after studying the writings and studies of Bible Scholars I have found that it is more likely that many of these ideals of Jesus that are considered "traditional" are in fact post-Christ ideals (post-Easter Jesus as Borg would call it). What people thought about Jesus and developed around the idea of him long after he was dead and gone.
If we trace back the dates of the writings of Jesus the gospels come up quite short. John comes up somewhere in the 2nd century (somewhere around 100 years after Jesus lived and died), The synoptic gospels shine through earlier with Mark being the oldest at most likely around 70 AD, with the other two being based off of Mark as well as other documents (one of those speculated as the "Q Document").
What's interesting is the most likely earliest writings we have are Paul's
authentic letters. 7 out of the 13 are considered authentic and date back old enough to be considered authentic, the rest do not.
Paul didn't walk with Jesus (by his own words) and hence didn't write much about what Jesus directly said and did, moreso what Jesus meant to him.
The irony of this is the most authentic writings of Jesus we have are actually the traditions and ideals that began to develop after he lived and died. We don't have an accurate historical representation of what Jesus actually did...
We can, however, piece together a historical Jesus among the writings that do exist. Specifically the synoptic gospels. Mark being the oldest and then the things shared among Matthew and Luke (that are not found in Mark, hence coming from another text that is possibly older than the gospels) can give us an idea of who Jesus was without the post-Christ traditions.
Just reading Mark and then John you can see the differences in how they viewed Christ from around 70 AD to most likely somewhere around 115-130 A.D. Quite a distinctly different Jesus. If we strip away what people thought Jesus was and distill it down to what is most likely true about Jesus and what most likely came from his own mouth we keep most of his parables and lessons in the gospels. What we are left with is lessons about how to live our life in the here in now, how to live in the Kingdom of God that is "within" us, in how we live a good life in helping others and by
not excluding others. By reaching out to those that are thought impure (sinner was a term they used for the impure).
We get a view of Jesus who rallied against the social injustices of his time, who is passionate about having a relationship with God. Now about following x rules to get into x afterlife, but experiencing God in the here and now and in helping others by not excluding them, by reaching out to those that are excluded.
What we don't get is a Jesus that ever implies he is dying for our sins, one that says he is God (most of this is taken from John which is most likely the
least historically accurate of gospels), and definitely not one in which the center of his life and purpose is how he died. In fact his death is not the focal point at all, it simply is a representation of him standing up for his beliefs knowing the cost was his life. Much more powerful an image than a lamb to the slaughter for a sacrifice.
Jesus is our savior because he showed us how to have a relationship with God by experiencing God in all sorts of ways, including through the act of including others that normally would be excluded.
If we are saved truly by grace then we cannot be saved by our choice in believing in the ideal that he died for our sins. That would be being saved based on our own decision, hence not of grace. Unconditional love and forgiveness ceases to be unconditional when you put a condition on it... and saying you must believe and/or have faith in Christ
is a condition (hence there lies the contradiction in such a belief).
Now you are welcome to hold to whatever belief you want, that is your right

Though I absolutely disagree that Jesus was perfect and he was a lamb sacrificed for us in that sense. In another sense he was a lamb sacrificed for us, he died showing us how to stand up for our beliefs and died for not compromising. That is the ultimate statement of faith.
