Digixx 0:1e4aa22fc1a1 2 * @author Peter Swanson
Digixx 0:1e4aa22fc1a1 3 * A personal note from me: Jesus Christ has changed my life so much it blows my mind. I say this because
Digixx 0:1e4aa22fc1a1 4 * today, religion is thought of as something that you do or believe and has about as
Digixx 0:1e4aa22fc1a1 5 * little impact on a person as their political stance. But for me, God gives me daily
Digixx 0:1e4aa22fc1a1 6 * strength and has filled my life with the satisfaction that I could never find in any
Digixx 0:1e4aa22fc1a1 7 * of the other things that I once looked for it in.
Digixx 0:1e4aa22fc1a1 8 * If your interested, heres verse that changed my life:
Digixx 0:1e4aa22fc1a1 9 * Rom 8:1-3: "Therefore, there is now no condemnation for those who are in Christ Jesus,
Digixx 0:1e4aa22fc1a1 10 * because through Christ Jesus, the law of the Spirit who gives life has set
Digixx 0:1e4aa22fc1a1 11 * me free from the law of sin (which brings...) and death. For what the law
Digixx 0:1e4aa22fc1a1 12 * was powerless to do in that it was weakened by the flesh, God did by sending
Digixx 0:1e4aa22fc1a1 13 * His own Son in the likeness of sinful flesh to be a sin offering. And so He
Digixx 0:1e4aa22fc1a1 14 * condemned sin in the flesh in order that the righteous requirements of the
Digixx 0:1e4aa22fc1a1 15 * (God's) law might be fully met in us, who live not according to the flesh
Digixx 0:1e4aa22fc1a1 16 * but according to the Spirit."
Digixx 0:1e4aa22fc1a1 17 *
Digixx 0:1e4aa22fc1a1 18 * A special thanks to Ewout van Bekkum for all his patient help in developing this library!
