Rich Ruler and Jesus Christ
Remember the story about the rich ruler? Jesus looked after the rich young ruler as he walked away, but Jesus did not follow him or attempt to coerce him. Jesus wants people make their own moral choices; and Christ knew this and permitted rich ruler to go his own chosen way. Jesus is saying that He cannot do our repenting for us. He died for our sins, now it is up to us to pick up the cross. "Salvation is free, ... but discipleship will cost you your life." (Dietrich Bonhoeffer)
A disciple must understand that God is both holy and loving; that I am a sinner, are made in the image of God; that Christ's death was the substitute payment for my sin; and that because of Jesus' payment, I am granted access to the heart of God.
Luke 14:27 And anyone who does not carry his cross and follow me cannot be my disciple. Luke 14:33 In the same way, any of you who does not give up everything he has cannot be my disciple.
