| 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! |
