Just as we "were" crucified with Christ according to scripture, we also died (past tense). But because we "follow" Him "but each one in his own order" (according to Paul) "we who are alive and remain" (also according to Paul), which was foreshadowed by Christ before He ascended after being resurrected. We too walk out our last days upon this earth and then ascend.
I believe I see what you are getting at, and if so, then I like it very much and even are starting to practise it.
You appear to be saying we ought not consider walking as Christ as he did before His death, but also after His resurrection on earth. The point being that Jesus is the same, yesterdy, and today, so that whether in natural flesh or immortal flesh, He walks the same on earth. With this in mind we ought also not consider our natural flesh as much as imagine and look for our immortal bodies, and endeavor to live that way. We think less of our body's mortality, and more of our newly resurrected immortal body to come.
In this way, we envision walking on earth as Jesus did for 40 days with immortal flesh and bone.
However, the confusing part is when you apply remaining alive on earth to being as Jesus for our last '40 days' before ascension. The problem with that is that remaining alive applies also to physical as well as spiritual. To say we are therefore remaining alive on earth
the same as Jesus did for 40 days, is teaching
we also have His immortal body alive and remaining on earth, while being spiritually pure as He, and living righteously and holily as He.
I completely agree with envisioning and conducting ourselves,
as though were were one with Christ during His 40 days in spiritual purity and manner of life, but we cannot yet be the same as Him
physically. We can imagine ourselves as being the disciples walking with Him at that time, but they were still in mortal flesh and blood, and not walking as Him with resurrected flesh and bones.
The benefit of the teaching, that is see, helps us to further perfect holiness in the fear of the Lord,
as though we already have resurrected bodies. The danger is then to actually believe it. That is the delusional pride that leads to a crashing fall.
It's like Simon the magician in the movie the Silver Chalice, where he actually began to believe he could fly, flew off the tower straight into the dirt.
If we actually believe we have attained immortal bodies on earth, like Jesus during His 40 days, then we will not only believe it is possible for us to never sin with the flesh, but also believe we can no more even be tempted. That is only for God on the throne, Jesus christ resurrected from the dead, and the first resurrection of the church.
This teaching of yours acting
as if we already have arrived, can lead to the surety of our calling, so that we shall not fall (2 Peter 1), but we will always need to continue enduring temptation of the devil and resisting him, so long as we are alive and remaining
in mortal bodies on earth.
You don't believe you now have the resurrected physical body of Jesus during your own '40 days' of remaining alive on earth, do you?
"we who are alive and remain" (also according to Paul), which was foreshadowed by Christ before He ascended after being resurrected. We too walk out our last days upon this earth and then ascend.
By saying Jesus' 40 days on earth in resurrected immortal body,
is a foreshadowing of us walking out our own last '40 days', are you not saying we are walking with immortal flesh and bones as He, and not just with Him in the Spirit and blameless living?
No, but rather that we have already died--not "in the flesh", but "to the flesh"...just we have also been crucified with Christ "already." Which is a matter of fully understanding the difference between the times of this world and God in whom there is "no shadow of turning", no sun, no moon, no evening, no morning, and no time.
This is the gospel message that we are spiritually alive in Christ, while remaining in the flesh, and dead to sins and trespasses of the flesh, so that we live as He,
before and after His resurrection;), in righteousness and true holiness. We now patiently wait for our own death, burial, and resurrection,
while eschewing evil and overcoming temptation. We are now of His flesh and bones spiritually in the inner man, but we have not yet recieved our own resurrected immortal physical body.
We will not walk on earth immortally as He did for 40 days, until He comes again and we reign and rule with Him the nations of the earth.
