It would help if you responded to all the points to have a fruitful discussion - maybe I’ll take something good from the conversation.
I wait for your response to the other points as to the above;
Not that I disagree as such with you state & I’m far from perfect;
1) but what source / moral code do you use to define sin?
2) Is there any difference / levels of sin - is murder the same as shoplifting?
3) does 1 have more consequences then the other?
Fair enough.
The moral code is the Law. Jesus stated that ALL the Law and prophets are fulfilled in the first two of the ten. The question, then, becomes to what extent do we seek to obey ALL the moral absolutes of all Gods word?
1) The simple answer is ALL moral absolutes outlined throughout are good to pursue. Faith above all as the means by which we receive salvation is by grace through faith. Paul stated nothing about obedience in the context of salvation. However, he spoke much about the moral standards of conduct and humility in all things. The rundown of the references would be overwhelming in a post, but personal study on this will produce the fruit of understanding that our salvation being to the uttermost by faith, sealed by Holy Spirit, given the earnest of Holy Spirit, born anew and immersed into Gods power of Sanctification, the questio melts away.
2) In Hell, there are degrees of punishment for the sins committed, with Satan receiving the greatest punishment over all others. Romans 2:1-16 is a good section for study, reading it carefully, word for word, digesting the nuances and tid-bits so easily overlooked when reading it like a novel. Paul speaks of those who are saved and who are not saved in his comparative dissertation. The unbelieving religionists treasure up wrath (v. 5) in God's judgement, but the truly righteous receive glory and honor (v. 10). If a true believer falls away into unbelief, many evil people are quick to judge then as having lost their salvation, and they don't MM without walking innthatnpersons shoes.
2 Timothy 2:13 — If we believe not, yet he abideth faithful: he cannot deny himself.
So, in Heaven too, there is degree of reward for good works versus the sins committed.
1 Corinthians 3:15 — If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
3) Yes, as covered thus far in this post. There are crowns and there are other rewards, although we have not been given specifics si ce eye has not seen nor ears heard, nor have any imagined, what's in store for us in the Heavenlies. We are destined for Heaven, not the New Earth or New Jerusalem. Modern and historic Jerusalem is Babylon, as Peter called it in his epistle, but the body of Christ, being under grace (unmerited favor), we will have our rewards in the Heavenlies as scripture states.
Granted, there are those who disagree and are on the side of works-based salvation. Their shoes I will not put on. They stand alone in their belief in some sort of lack in the effectiveness they think exists in the shed Blood of Christ Jesus. Their trust in their works may be their undoing. Not my call. They are on their own. As for me, I will only trust in Christ and what He did for me rather than to hold up to Him my resume as if itnhad any merits in relation to the cross.
Hope that helps.
