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