"Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come." (2 Corinthians 5:17)
Left to ourselves, people tend to make a mess of things. There is a universal problem called "sin" that manifests itself in many ways ... some sins are subtle, some are sick and sad, all lead us on a path to destruction.
The only solution to this problem is for us to give up our own efforts of saving ourselves and to put our complete confidence in what Jesus did on the Cross.
The main elements of this change are:
* Justification: You are accepted in Christ
* Sanctification: You are free from bondage to sin in Christ
* The Indwelling of the Spirit: You are not alone
* Authority in Spiritual Conflict: In Christ you have authority
All this is rooted in the Gospel of Jesus Christ.
