The torcher which Jesus experienced during His trial along with the time He endured on the cross is not what we deserve for our sins.
Physical death is not even what we deserve for our sins (Physical death is only a consequence for not eating of the "Tree of Life").
The desert of sin is spiritual death, and after physical death (if still spiritually dead) we deserve eternal separation from God.
Since spiritual/eternal life after death is to be in the presence with God eternally, then to die without spiritual/eternal life is eternal death, which is eternal punishment.
This is because if one does not stay in the presence of Christ, there is no other place to be but in outer darkness where there is gnashing of teeth.
Therefore, Jesus could not have suffered the full wrath of God. He did not suffer the punishment which we deserve, and He never could (even if He had sinned).
We deserve spiritual death, and if we are not reconciled to Him, we deserve eternal separation from God.
Jesus never experienced that; He never could.
Furthermore, there is no possible way that anyone to have a substitute for punishment of a crime such as murder.
It isn't even possible in a moral government judicial system as we have in society.
For example, a father could never take a son's place in his execution for murder. Furthermore, a King could never let a law breaker go free as in the case of Daniel and the lion's den.
Hebrews 2:17 Therefore in ALL THINGs he had to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people.
Hebrews 2:18 For in that he himself has suffered being tempted, he is able to help them that are tempted.
There is nothing about Jesus needing to experience our self-inflicted helplessness, our dependency, our depravity, or even our brokenness... or even our self-inflicted “addiction” to sin
All He needs to know by experience is the temptation of sin, of which He tasted fully.
Yes, Jesus really can know the love/hate relationship towards sin that a believer struggles with.
Jesus was starving after 40 days in the wilderness; He loved the thought of satisfying His appetite which He had at the time.
Along comes the thought of turning stones into bread (the stones in that area actually looked like real loaves of bread which compounded the temptation
Furthermore, He was the Son of God; He was able to such?)
No, it is not true that temptations fluctuate from individual to individual depending on any circumstances.
Sin is sin, and it does not matter what sin anyone is tempted of; or even how grievous of sin. All that matters is that we are tempted to sin and that Jesus was also.
And no, it isn't true, that those who tend towards sin have a greater temptation, and a greater willingness to sin.
It doesn’t matter about the intensity of temptation. If it did, who’s to say that Jesus never experience the greatest in intensity?
All mankind only “tends” toward that which they choose to favor/desire.
The only reason that anyone would have a “greater temptation” or a greater willingness to sin is because they choose to have a greater desirer for it.
Your question might be:
What is it that causes us to choose our affections?
The answer:
There is a time when a child does not know to choose good or evil (Isa 7:16); this must be taught. We must be taught correct values for our assessment of right & wrong; we must be taught, that we may be able to discern. Our conscience will confirm what is right or wrong even if it is weak.
Therefore, that which "causes" us to choose our affections are the values that we have assembled of our own volition.
That which makes our values are the things which become important to us. The things which become important to us are our own evaluation of the eternal compared to the temporal.
Knowing that God has set eternity in all mankind’s hearts (Ecc 3:11)
If we live for this life only, well then...
However, if we are living for the next life, which is eternal, well then...
The knowledge of God is the beginning of wisdom (Psalm 111:10, Prov 1:7; 9:10)
