Unforgivable sin? Is there anything that God cannot forgive? There is only one sin that will not be forgiven, and that is the rejection of Jesus Christ. Jesus is the way to be forgiven, His blood was shed for our sins and he died and was resurrected to eternal life. This secured our salvation. We need only believe that He did this for us.
Romans 3:23 For everyone has sinned; we all fall short of God’s glorious standard.
24 Yet God, with undeserved kindness, declares that we are righteous. He did this through Christ Jesus when he freed us from the penalty for our sins.
25 For God presented Jesus as the sacrifice for sin. People are made right with God when they believe that Jesus sacrificed his life, shedding his blood. This sacrifice shows that God was being fair when he held back and did not punish those who sinned in times past,
26 for he was looking ahead and including them in what he would do in this present time. God did this to demonstrate his righteousness, for he himself is fair and just, and he declares sinners to be right in his sight when they believe in Jesus.(NLT)
2Cor 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
You become a new spiritually alive person. Your future is everlasting as a son or daughter of God. You shall be with Jesus forever.
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
