higedura 0:80d32420bc63 3 * A personal note from me: Jesus Christ has changed my life so much it blows my mind. I say this because
higedura 0:80d32420bc63 4 * today, religion is thought of as something that you do or believe and has about as
higedura 0:80d32420bc63 5 * little impact on a person as their political stance. But for me, God gives me daily
higedura 0:80d32420bc63 6 * strength and has filled my life with the satisfaction that I could never find in any
higedura 0:80d32420bc63 7 * of the other things that I once looked for it in.
higedura 0:80d32420bc63 8 * If your interested, heres verse that changed my life:
higedura 0:80d32420bc63 9 * Rom 8:1-3: "Therefore, there is now no condemnation for those who are in Christ Jesus,
higedura 0:80d32420bc63 10 * because through Christ Jesus, the law of the Spirit who gives life has set
higedura 0:80d32420bc63 11 * me free from the law of sin (which brings...) and death. For what the law
higedura 0:80d32420bc63 12 * was powerless to do in that it was weakened by the flesh, God did by sending
higedura 0:80d32420bc63 13 * His own Son in the likeness of sinful flesh to be a sin offering. And so He
higedura 0:80d32420bc63 14 * condemned sin in the flesh in order that the righteous requirements of the
higedura 0:80d32420bc63 15 * (God's) law might be fully met in us, who live not according to the flesh
higedura 0:80d32420bc63 16 * but according to the Spirit."
