The difference between salvation & discipleship

There are many who are saved who are not yet disciples. The old saying goes " salvation is free, but discipleship costs everything." Salvation is trusting in Jesus Christ alone and His finished work on the Cross as your only means of going to heaven. Discipleship requires you to be crucified with Christ resulting in putting to death sin and self interests. When one does not die to sin, the Old Man continues to live. But when you die to sin and to self, the result is a new nature apart from worldliness. The first step after salvation is to agree with Christ about your sin. The second is putting it to death with the help of the Spirit so that you can walk in newness of life.
