The church and the Christian and the gospel are not so much concerned about removing the occasions for sin as removing from man the desire to sin.
“I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil…. Sanctify them” (John 17:15, 17).
Our Lord is saying in effect, “I am not so concerned that You should take the occasion for sin away, but that You should take out of the man the desire to take advantage of the occasion.”
Dr. Martyn Lloyd-Jones
The Gospel of Jesus Christ does not so much take the Christian out of the world as take the desires of the world out of the Christian.
