God's word is true-sin is sin

When I was working with Child Evangelism Fellowship, there was a great and simple definition as to what sin is. "Sin is anything you think, say or do that displeases God". So why do we as Believers in Christ haggle over what is right and wrong in God's eyes, twist what He says in His word to fit what we are doing in our lives? I was asked if I believed that a certian lifestyle could be changed or not. When I answered, that no it can't, there was a reason behind it. A person can not change what they don't acknowledge. (Yeah Dr. Phil!) If a person is not going to acknowledge that what God deemed to be sin, they aren't going to accept it and are not willing to change, but will make excuses for it to be acceptable for themselves and those around them. And God has no use for them if they continue to live a life of rebellion. God's word is very clear, if we take out something to fit our fancy, then His word become useless because it is His whole word that makes us alive in Him. It is Rheama and Logos. His word makes us accountable. Its not a bunch of rules because rules make it religious, and God's not into religion, He's into our lives. If we say that we are with out sin and live our lives like we want and twist His word around, then we are calling God a liar. And again we are making the book He gave us to live by, just a book. It has no value to it at that point. God's word is living and breathing. It is alive, every bit of it is truth. His word is truth. He give His believers freedom when they do confess their sins. When we acknowledge that our lives do not line up to His word, and confess our sins, He is FAITHFUL and JUST to forgive us our sins and cleanse us from all unrighteousness. (1 john 1:9) "Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. " (1 Cor. 6:9-10). So either we believe that what was written in Corithians is true and God's guidelines to what sin is in these verses or we throw the baby out with the bath water. God clearly states that even symbols in the Bible can't be changed or taken outwith out reprecussions from it (Matthew 5:18) , why would we take out or change words from it as well? Christ came to fulfill the law not to change it, and nothing in His word needs to be changed. We need to stop walking on the fence on this issue becuase the fence is coming down and there will only be a line drawn in the sand where the fence was. What side of the line will you be on?
