Growing up in a Christian home or even following a moral code does not make you a Christian. Being a Christian means you have come to the end of yourself and have realized that you need a Savior. God doesn't keep a report card of your failures, waiting to strike you with punishment every time you mess up. Though He does want us to pursue holiness, striving to glorify Him in all that we do.
"But know this, that in the last days difficult times will come: For men will be....lovers of pleasure rather than lovers of God;
Having a form of godliness but denying it's power." (II Timothy 3:1-5)
