ryought 0:cda6d9f5a43c 2 * @author Peter Swanson
ryought 0:cda6d9f5a43c 3 * A personal note from me: Jesus Christ has changed my life so much it blows my mind. I say this because
ryought 0:cda6d9f5a43c 4 * today, religion is thought of as something that you do or believe and has about as
ryought 0:cda6d9f5a43c 5 * little impact on a person as their political stance. But for me, God gives me daily
ryought 0:cda6d9f5a43c 6 * strength and has filled my life with the satisfaction that I could never find in any
ryought 0:cda6d9f5a43c 7 * of the other things that I once looked for it in.
ryought 0:cda6d9f5a43c 8 * If your interested, heres verse that changed my life:
ryought 0:cda6d9f5a43c 9 * Rom 8:1-3: "Therefore, there is now no condemnation for those who are in Christ Jesus,
ryought 0:cda6d9f5a43c 10 * because through Christ Jesus, the law of the Spirit who gives life has set
ryought 0:cda6d9f5a43c 11 * me free from the law of sin (which brings...) and death. For what the law
ryought 0:cda6d9f5a43c 12 * was powerless to do in that it was weakened by the flesh, God did by sending
ryought 0:cda6d9f5a43c 13 * His own Son in the likeness of sinful flesh to be a sin offering. And so He
ryought 0:cda6d9f5a43c 14 * condemned sin in the flesh in order that the righteous requirements of the
ryought 0:cda6d9f5a43c 15 * (God's) law might be fully met in us, who live not according to the flesh
ryought 0:cda6d9f5a43c 16 * but according to the Spirit."
ryought 0:cda6d9f5a43c 17 *
ryought 0:cda6d9f5a43c 18 * A special thanks to Ewout van Bekkum for all his patient help in developing this library!
