I am a Christian and I will boldly tell you today that I still do struggle with sin from time to time; I don't always keep all of the Ten Commandments penned in exodus 20. Is it because I am evil and want to disobey God? No it is because Christians are equally and just as human as the rest of the world's people are.
Paul wrote in Romans 7:15, "In fact, I don't understand why I act the way I do. I don't do what I know is right. I do the things I hate." This is a miserable state for the Christian, Paul said in Rom 7:13 "Was then that which is good, death to me? In no way. But the purpose was that sin might be seen to be sin by working death to me through that which is good; so that through the orders of the law sin might seem much more evil."
Not only does sin seem much more evil for the believer but the believer is furiously fighting to limit his daily dose of sin, so to be sure this is certainly a miserable state of being as Paul again said here, "Wretched man that I am! Who shall deliver me out of the body of this death?"
After imparting the ten commandments God offered, "I call heaven and earth to witness against you this day, that I have set before thee life and death, the blessing and the curse: therefore choose life, that thou mayest live, thou and thy seed"
With this offer by God in view one can only imagine how Paul must have been feeling when he wrote the above words.
Now the gist of this thread. If man is inseparable from his sin than he must be doomed (Proverbs 13:6 Live right, and you are safe! But sin will destroy you; Romans 6:23 for the wages of sin is death.).
And if Paul one of the trend setters in Christianity complained about sin how much harder it would be for the one who is of the world to escape destruction through his own sin. And also what is the purpose of the Ten Commandments if they seem not capable of being put into practice. And furthermore what made Paul so confident and stable in his ministry when simultaneously he complained about sin, why was he so certain that he would escape destruction?
I think these are honest questions that everyone asks on the odd occasion. But before we can set out with this topic there is one question I'm sure that will almost certainly always pop up, and that is, "is there such a thing as sin?" Well I think there is by definition sin is a transgression of God's will, missing the mark set up by God. This is what sin is and considering the Ten Commandments and considering our present states I would say that sin is altogether alive and doing well.
Any honest person will admit that he/she has committed sin not once or twice or thrice but a good number of times. I remember an old hymn at this point, "My sins are higher than the mountains." Indeed we are so dispirited by the magnitude of our individual sins, but then tally up our individual sins and then put on God shoes, and experience the kind of mental depression he must be suffering each day that he allows sin to hang around. We are terribly sinful creatures our very nature is sinful, perhaps sin possesses a locus on our chromosomes. Whether or not this is the case no one can deny the existence of sin.
