Whilst I can understand where you are coming from, and I do agree with that trail of thought, but only to a certain degree.
Is it imcompatable with the christian faith to presume a sinner will keep sinning?
We are all sinners and will continue to sin.
We have all fallen short of the glory of God.
it is not whether they will always continue cheating as it is so much that they will cheat again, once they have done so.
I don't follow this part. I understand they like us are sinners and will continue to engage in sin. But that doesn't mean they will always cheat on their partner or spouse.
Yes but that is not my point.
The point was that someone will only change when there has been true repentence. Not when someone can identify when, or if that has occured.
See I disagree with this on the basis of theology. Thats because I don't believe that once someone has truely repented of a certain sin that they will therefore NEVER commit that same sin again.
That is like saying if I get upset with someone and act in an unloving manner. If something like that ever happens again it means that I never truely repented of it in the first place. I belive you can truely repent of something (be truely sorry for it.) but do a similar or the same thing again in the future. True repentance does not grant one immunity from any sin.
Christian logic?
What is christian logic?
Is it a form of logic that differs from other sorts of logic?
Its logic based on the principals of the Christian faith. It might not solve math problems for you or things like that but Christian logic is applied in a lot of situations without you thinking about it.
For example. . . what ultimatly decides if something is right or wrong?
Christian Logic. . . God decides and we can understand what he thinks on a subject via the scriptures. If God says its wrong its always wrong.
Worldly Logic . . . The law and the individual person decides. But sometimes the law is wrong and sometimes the individual person is wrong.
What is the point of life.
Christian Logic . . . To love and serve God & neighbor.
Worldly Logic . . . To feel good.
It may be a term I invented but you get my point. The logic of a Christian especially on the most important and crucial questions of life varies quite differently and comes to completly different conclutions then that of non-Christians.
