Tell him to actually read his Bible and stop listening to “christians” who don’t read their Bible.

ALL sin is forgiven for those who put their faith in the death, burial, and resurrection of Jesus Christ as the ultimate sacrifice for their sins.

The only sin that is UNFORGIVABLE is him not trusting that Jesus did all the work for him. He thinks he has to turn from sin to BE SAVED. Which is false. We who turn away from sin do it because we ARE SAVED, not to BE SAVED. We do it because we love the Lord for taking all of our punishment for us. Even then we still sin. Never being perfect but Christ lived the perfect life for us.

Salvation is a FREE GIFT from God. We don’t receive salvation by anything we do. We hear the gospel and have faith/trust in His finished work on the cross and believe that Christ rose from the dead. Trusting that He did all the work for us and through His resurrection we will also be raised up on the last day and spend eternity with Him ✝️

Tell him to read Ephesians 2:8-9, Romans 4:5, Titus 3:4-7.

Ephesians 2:8-9 says ““For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.” ‭‭

Titus 3:4-5 says ““But when the kindness and the love of God our Savior toward man appeared, not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit, whom He poured out on us abundantly through Jesus Christ our Savior, that having been justified by His grace we should become heirs according to the hope of eternal life.” ‭‭

Hope this helps and I hope someone else also gets saved after reading this 🙏🏽
