For A: Jesus need not to die , He would have simply say "sorry" to Jews/romans and live
Who said He needed to die? His death was somewhat of an inevitability since His teachings were so radical and threatened those that were in power but it certainly wasn't some kind of prerequisite. What would saying, "sorry" do and why would He say it? He wasn't sorry for bringing the light of God to mankind, just the opposite.
A is simply following a footpath or following rules
Actually that's "B". "A" is saying rules AND a path to understanding and Truth and learning to SEE the light of love and to love God.
Christ died in vain if we can be saved by the Law of Moses - Galatians 2:21
Absolutely true. We couldn't have been saved by the law of Moses alone. Christ took things to a new level when we were ready.
Therefore the very Law people desire to save them holds them under the condemnation of death - Romans 3:19-20
When a man desires to bind a portion of the Law, he declares the work of Christ to be useless - Galatians 5:2-4
Not sure what you mean by these.
The Bible says that all have sinned and fallen short of the glory of God (Rom. 3:23).
Because God is perfect and we are not.
That means that your sins have caused a separation between you and God (Isaiah 59:2)
Right, because again God is pefection and sin is the absence of perfection and the disobedience of spiritual laws that govern our souls? ("laws" meaning simple truths like the law of gravity)
and the result is death (Rom. 6:23)
Physical or spiritual?
Painful realization of the Truth? Learning the hard way?
The only way to be saved from the wrath of God, is to be saved from it by faith in Christ (Eph. 2:8-9; Rom. 5:1).
Putting trust in Jesus that He knows more than you about your own very nature and the spiritual laws that govern your soul so that you can be guided toward the light of Truth and God's will without going through the anguish of learning the hard way?
Jesus died for sinners on the cross
Why not "A"?
His death was a sacrifice that turns away the wrath of God (1 John 2:2). This is the only way to be saved.
Jesus is the one who died for the sins of the world (1 John 2:2).
Why not metaphorical for "A"?
He is the only way to the God the Father (John 14;6). He alone reveals God (Matt. 11:27). He has all authority in heaven and earth (Matt. 28:18). It is only through Him that you can be saved from God's wrath (Eph. 2:3).
God is all-powerful and the absolute Truth and Jesus was the only man anointed with the light of that Truth to shed some of that light on mankind who would be lost in the dark on his own?
He can forgive you of your sin (Luke 5:20; Matt. 9:2). He can remove the guilt that is upon your soul. Jesus can set you free from the bondage of sin that blinds your eyes, weakens your soul, and brings you to despair.
Darkness turned to Light and falsehood to Truth? In other words He lets man see the good in Good so that he can use his free will to attain it?
He can do this because He bore sin in His body on the cross (1 Peter. 2:24) that those who trust in Him would be saved.
Why not metaphorical for "A"?
