Have you given up your illusions of spiritual health to follow the Savior? Have you chosen to be a Matthew or a Pharisee?
If you have made that initial decision to become Jesus' disciple, are there any areas in your life that you are reluctant to surrender to Him? Have you held back a portion, thinking somehow that parts of you are not sick enough to receive attention from the Physician, hoping that He'll allow you to keep those parts hidden and focus only on the areas you choose? When He has so much to offer, is what you have truly so much better, truly worth holding onto?
