higedura	0:f5a5a0e5fefb	2	* @author Peter Swanson
higedura	0:f5a5a0e5fefb	3	* A personal note from me: Jesus Christ has changed my life so much it blows my mind. I say this because
higedura	0:f5a5a0e5fefb	4	* today, religion is thought of as something that you do or believe and has about as
higedura	0:f5a5a0e5fefb	5	* little impact on a person as their political stance. But for me, God gives me daily
higedura	0:f5a5a0e5fefb	6	* strength and has filled my life with the satisfaction that I could never find in any
higedura	0:f5a5a0e5fefb	7	* of the other things that I once looked for it in.
higedura	0:f5a5a0e5fefb	8	* If your interested, heres verse that changed my life:
higedura	0:f5a5a0e5fefb	9	* Rom 8:1-3: "Therefore, there is now no condemnation for those who are in Christ Jesus,
higedura	0:f5a5a0e5fefb	10	* because through Christ Jesus, the law of the Spirit who gives life has set
higedura	0:f5a5a0e5fefb	11	* me free from the law of sin (which brings...) and death. For what the law
higedura	0:f5a5a0e5fefb	12	* was powerless to do in that it was weakened by the flesh, God did by sending
higedura	0:f5a5a0e5fefb	13	* His own Son in the likeness of sinful flesh to be a sin offering. And so He
higedura	0:f5a5a0e5fefb	14	* condemned sin in the flesh in order that the righteous requirements of the
higedura	0:f5a5a0e5fefb	15	* (God's) law might be fully met in us, who live not according to the flesh
higedura	0:f5a5a0e5fefb	16	* but according to the Spirit."
