"Why didn't God simply change sinful men back to the original state since God created them in the first place ?"is a very good question you have raised.
The tough part this Q has been involved is what has been broken is the relationship with God, not just a broken arm, leg or an organ that can be fixed easily. To mend a broken relationship is easy said than done, otherwise, there won't be so many divorces in our world, right? Also, it involves both sides willing to reconcile, if only one side is willing to mend the relationship, it won't work. Say, if only the husband or the wife who wants to reconcile, the incompatibility will continue and the divorce will proceed, no turning back.
So now it is humankind who rebels against God and walks away from Him. Men have broken the trust in God and their precious relationship with their Creator God. God being absolutely holy can't embrace sinners back by drinking a cup of coffee as you said.
Sins are absolutely incompatible with God's absolute holiness, sins we shrugged our shoulders at, are horrible in God's sight, do you realize that? God's holiness can't be contaminated by our sins. There was a big chasm between our Creator God and sinful human beings. And Jesus is the only Way to God ( the only Bridge that brings us to cross the sin chasm between God and us.)
God being the righteous Judge has to condemn sinners to death penalties yet God being our loving Creator God Himself( God the Son, Jesus Christ being incarnate God/man) had substituted us to suffer the consequences of sins--death on the cross. On the cross, Jesus bore all our sins and paid our debts
( sins). Thus, whoever wants to restore the relationship with our Creator God can simply accept Jesus' sacrificial offer and be reconciled to God. God the Holy Spirit can then indwell in true believers whose sins were cleansed by Jesus' blood.
As it is a relationship so it needs both sides to agree to restore the former spiritual relationship. God has sacrificed Himself to make this reconciliation possible, yet God honors our free wills and won't force on us. He is waiting for you to turn to Him. The day you say" I do!" to God's salvation offer in Jesus is the day you can become God's adopted son.( Not "Son", nobody can be the Son except Jesus.)
I can only pray that day will come sooner!!! I hope you see how our loving God can't force this salvation on you, without your acceptance and agreement, the reconciliation won't work even though Jesus had paid dearly with His own life for the foundation of reconciliation. Dear SS, Jesus has really died for you, don't harden your heart!
You always question why Christians could be smarter than the non-believing Jews and know better about God, and I have told you it is because of God's grace and it is SQ( spiritual quotient) not IQ. in Christians' part. So they are not smarter than the non-believing Jews, than non-believer ( PhDs like you...etc.) but they are spiritually restored to God and have the relationship with a living Trinity God. That is the difference, not smartness at all. Otherwise, you should know much better than me.
When I woke up this morning, "the chasm" is ringing in my ears, so I googled the images of chasm and here are the 2 links The Problem: A Gap Caused by Sin,Sin's Chasm: Human Efforts Fall Short Indeed a picture can say better than a thousand words.
God bless you and yours,
May God open your spiritual eyes to see His truth!
