Have you ever wondered as a Christian, are we supposed to just "learn to live with" sin?  Is that God's plan for his people who were bought by the blood of the lamb?

"Boys will be boys", and "We're only human" are not the words we will be judged by, but rather by the Words God has spoken and recorded in the Bible for us. 

You could be walking on some thin ice, and I suggest you prayerfully consider what God's word has to say about your life's situation.

According to the Bible's teaching, being saved by grace doesn't mean you continue in habitual sin.  Our lives are to be lived for the One who bought us.  We are to be radically changed from what we were before Christ.

Romans 6:1-3 What shall we say then? Shall we continue in sin that grace may abound?  Certainly not! How shall we who died to sin live any longer in it?  Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? Romans 6 (Whole Chapter)

There is a state of heart talked about in scripture that is not mentioned much from the pulpit today.  Since you may not hear about it otherwise, you would do well to heed the Bible's warnings to the "Christian" with a hardened heart...

I want to see some Scriptures to back this up.
