Christ changes lives. 22 years ago He changed mine - RADICALLY! I am not who I once was and am overwhelmingly humbled by that fact! He makes old things wonderfully new, disposable things to be of eternal value, dead things eternally alive, and sinful things gloriously righteous. What has He made you?
If you have not been changed then it may be wise to ask yourself if you have been saved. Christ did not save us to leave us as we were.
Adam Clarke in his comentary on 2 Corinthians writes: "It is vain for a man to profess affinity to Christ according to the flesh, while he is unchanged in his heart and life, and dead in his trespasses and sins." Oh, God - spare us from this form of vanity.
Your past may not have been as checkered as my own but we all are under the fall's curse, we all are by nature children of wrath, and we all are in bondage to sin. Bottom line - we all need to be changed.
HAVE you been changed? Are you different since meeting Christ? If the answer is no, may I be so bold as to question you as to whether you have every truly met Him.
He makes the slave to be free. He makes the proud to be humble. He doesn't merely fix us up, He makes us new. He makes us a new creation. That which was chaotic and without order is now made a masterpiece by the Master Craftsman. Are you among His prized creations? In Christ, you can be.
