Romans 6:4-5
4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
When we come to God, we are born again. We become new creatures in Christ. We do not realize that a part of us does die. The man we had been dies. We are reborn as a new creature in Christ. The problem is many try to keep their old life on life support. They think if it is there then they can always go back to it if the christian life does not work out. You cannot do this. We are to let that life die. We are to let the past fade away. In this we share a new life in Christ. It is truly time we all pull the plug on our old life and let it die.
