Frederick_H 3:e4783c57bcc0 3 * A personal note from me: Jesus Christ has changed my life so much it blows my mind. I say this because
Frederick_H 3:e4783c57bcc0 4 * today, religion is thought of as something that you do or believe and has about as
Frederick_H 3:e4783c57bcc0 5 * little impact on a person as their political stance. But for me, God gives me daily
Frederick_H 3:e4783c57bcc0 6 * strength and has filled my life with the satisfaction that I could never find in any
Frederick_H 3:e4783c57bcc0 7 * of the other things that I once looked for it in.
Frederick_H 3:e4783c57bcc0 8 * If your interested, heres verse that changed my life:
Frederick_H 3:e4783c57bcc0 9 * Rom 8:1-3: "Therefore, there is now no condemnation for those who are in Christ Jesus,
Frederick_H 3:e4783c57bcc0 10 * because through Christ Jesus, the law of the Spirit who gives life has set
Frederick_H 3:e4783c57bcc0 11 * me free from the law of sin (which brings...) and death. For what the law
Frederick_H 3:e4783c57bcc0 12 * was powerless to do in that it was weakened by the flesh, God did by sending
Frederick_H 3:e4783c57bcc0 13 * His own Son in the likeness of sinful flesh to be a sin offering. And so He
Frederick_H 3:e4783c57bcc0 14 * condemned sin in the flesh in order that the righteous requirements of the
Frederick_H 3:e4783c57bcc0 15 * (God's) law might be fully met in us, who live not according to the flesh
Frederick_H 3:e4783c57bcc0 16 * but according to the Spirit."
