And punishable by execution according to OT Levitical law, stealing is a sin, but the punishment was restitution not death. Certain sins come with a bigger punishment. Now before the liberals go off the handle here, I'm NOT suggesting we execute people for sexual sin, just merely pointing out that homosexual is a serious sin and carried a bigger punishment then common sins.
this is not even remotely Biblical and you will have a hard time showing me where you dreamed this up at in the Bible.
SIN is SIN and it is not ranked, except for 1 and that is Blaspheming the Holy Ghost, which is simply unbelief in Jesus.
It is unbelief in Jesus Christ and his work on the cross that is the greatest SIN.
Here is the mind bending revelation for you on SIN:
A lost person has no idea what SIN is, because their mind as not been renewed, because their spirit still has no right standing with God, and their SIN nature dominates them. So here is the rub, if this young man is not born again, telling him he is living in SIN only adds to his confusion, Because the carnal mind is at enmity against God. He cannot understand spiritual things because his does not have the mind of Christ yet.
This is why so many fail at witnessing, because the natural man cannot receive the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. How does a lost person spiritually discern things of God? That is one of the works of the Holy Ghost: To reprove the world of sin. That is his JOB not YOUR job.
Telling a person of the world they are living in SIN is like talking to a deaf person. I have never experienced a person truly coming to Jesus based on fear. Preaching hell fire and damnation never works on the lost, because all you do is appeal to a persons sense knowledge of fear and they respond to the message out of fear and not by the reproving of the Holy Spirit.
In my experiences, when a lost person comes to Jesus they have always told me they felt a Love they have never known, a mercy that convicted them and a sense of goodness from God they could not describe, because that goodness said you are free and I love you despite...... this lines up with Romans 2.4, it is the goodness of God that leads mean to repentance and that by truth and mercy iniquity is purged.
Once a person is born again, they receive right standing with the Father, through Christ and that relationship is restored and the spirit has connection with God. Sadly most of the Body stops there and then beats the snot out of people for not living right, but the bible states we must renew our mind, because your mind was conformed to the world and not by the Spirit of God.
