Jesus, the lamb of God, bore our sins in His body on the cross. He is the lamb for our atonement. He was SACRIFICED and paid the penalty for all sins. God’s wrath and judgement against sin - all sin - was satisfied by Messiah on the cross. I am forgiven in Christ. I am righteous in Christ. I am healed (body, soul, spirit) in Christ. I have eternal life in Christ. We are the ones who choose life or death. The way to life, the only way to life, is in and through Christ. Sooo, whose righteousness are you depending on? If it’s your own, good luck with that. “For God so loved the world (mankind) that He gave his only begotten Son; that whosoever believe in Him shall not perish but have eternal life.” Jn 3:16
He does not believe nor “cling to guns or religion”. Ergo
He is doomed and thank providence for that
