2 Timothy 1:9
…who has saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace which was given to us in Christ Jesus before time began,
When you are born again you have been saved, delivered from God’s judgement that is to come to all who will not receive Jesus as the Lord of their life. He has taken our sin and the punishment our sin deserved when He gave His life for us on the cross. Notice in the above verse He has called us with a holy calling. This holy calling means to be set apart from a life of sin unto God. Sins ways are still destructive, but thank God we can live a life free from willful sin.
Romans 6:21 tells us to consider ourselves dead to sin, and alive to God. When you are born again the old sin nature within has been removed and you are given a new spirit. You need to begin to recognize that the old sin nature is gone. You do this by changing your focus in life, looking to Jesus and this new life He has given you. This is why Romans 12:2 tells us to renew our mind so that we will not be conformed to this world, but be transformed into this new life on the outside.
Romans 6:13 goes on to tell us we are to present the members of our bodies as instruments of righteousness unto God. We stop looking at, listening to, and associating with things that are sinful. If we don’t this allows the devil to take advantage of our life. Living a life holy, set apart unto God means you will experience the good, perfect, and acceptable will of God, which is far better and more rewarding then living in sin. Jesus did not give His life so we could continue in a life of sin, He died to free us from sin and it’s destructive ways. Consider yourself dead to sin, and give yourself to the ways of God and you can live in the new life He has called you too.
