Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation; To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
2 Corinthians 5:17-19
D. L. Moody was saved after his Sunday school teacher, Edward Kimball, cared enough to reach out to the young man with the gospel. Kimball came to the store where Moody worked and talked to him about his need for salvation. Later, Moody became one of the most powerful and effective evangelists the world had ever seen—his life being totally transformed by the power of the gospel. Moody wrote, “I remember the morning on which I came out of my room after I had first trusted Christ. I thought the old sun shone a good deal brighter than it ever had before—I thought that it was just smiling upon me; and as I walked out upon Boston Common and heard the birds singing in the trees I thought they were all singing a song to me. It seemed to me that I was in love with all creation. I had not a bitter feeling against any man, and I was ready to take all men to my heart.”
God does not save us to leave us as we are. His grace not only changes our eternal destination, but it changes everything about the way we live in this world as well. While we should be faithful witnesses for the gospel, it is not just our words that reflect the change God has made in our lives. The way that we think and act and respond are all meant to be shaped by the power of God's grace to make us positive representatives of His family. “Now when they saw the boldness of Peter and John, and perceived that they were unlearned and ignorant men, they marvelled; and they took knowledge of them, that they had been with Jesus” (Acts 4:13).
