As far as I am aware, according to Christian beliefs after Adam's fall all humanity became sinful and doomed to perdition. Then Son of God was sent by Father to save mankind and give eternal live for those believing in Him.
‌Why was all this needed? Why didnt God simply send a prophet with instructions how people can save themselves? Why did God have a need to make sacrifice for himself?
Dear
ESay the analogy I use to explain this process,
I compare it with installing an anti-virus cleanup program into a hard drive that is already infected,
where malware is already embedded in files and programs.
It isn't enough just to run it and then keep going.
the computer has to be shut down completely,
then rebooted for the program to infiltrate all the files and locations
and restart with the program fully embedded and protecting the system.
Jesus represents perfect Universal Laws of Justice coming from a divine level
and being sent down into man's corrupt worldly level already messed up.
So Jesus had to be incarnated INTO this system, then "killed off while on this level"
so that when the system is "rebooted" then there is synchronizing on all levels.
The purpose of this process of "establishing justice" is to reconcile
man's laws and life on earth with the higher laws of justice beyond our limited lives and perception as humans.
We cannot receive this higher justice if we continue to divide and reject
according to our manmade justice where we punish and judge each other by groups blaming one another.
We must forgive and let go the past garbage that junked up our system of justice;
in order to receive Mutual corrections to restore true peace and justice for all.
this is what it means for all people to submit to Equal Justice as the Law for All,
or Jesus being Lord of all. We are not in charge of justice that is greater than any of us.
This comes from higher level than just us, who as human beings are imperfect
and biased by our personal "conflicts of interest." We will always favor our own interests and groups we identify with, over groups we don't relate to, or we even exclude or reject other groups and don't treat each other equally. We are biased and not going to be perfectly fair
and all inclusive of all people. We are not that perfect in our judgment, so our justice system is flawed and fails to protect and include all people equally under law as the ultimate goal.
The point of divine grace is to break through the vicious cycle we cannot get out of
because we keep blaming each other in circles. Humans cannot forgive what we can't correct.
so it takes Divine Justice to correct these wrongs on a global scale of saving all humanity from injustice and wrongs, where we can forgive and heal
and one day learn to live in peace instead of living in the past.
