“the post-Christian atheist knows God exists, but he desires He should not.”- Ven Arch Fulton Sheen
Believe Jesus Christ is your savior for your sins. Jesus Christ is God Almighty in the Flesh. This is the Gospel, believe Jesus Christ shed his precious blood and died for you and all of your sins on the cross, he was buried and he rose again from the dead three days later from God's Power and you will be saved, you are a Born Again Christian and you will go to Heaven forever. All have sinned and fallen short of the glory of God to where we all deserve death, destruction and judgement in the Lake of Fire from the wrath of God to where we need a savior to save us for our sins forever. By receiving Jesus Christ's blood sacrifice as full payment for your sins you will be saved forever. It matters not how much you have sinned in the past, in the present and in the future for yourself to be saved. Once you are saved you are saved forever no matter what. Good works will not ever save you and no one and nothing else will. That is the Gospel and if you believe in the Gospel you are now a Born Again Christian and you are now saved and you will go to Heaven forever and that is the whole truth. Spread the truth. If we do good works for God as he commands, we will please God and he will give us rewards to have in Heaven forever! All glory goes to God forever! Praise God! Amen! (John Ch. 3:16, Romans Ch. 3:25, 4:1-6, 5:9, 1 Corinthians Ch. 15:1-4, Ephesians Ch. 2:8-9) The Authorized King James Version Bible.
You forgot to mention one cannot be saved unless you also accept the authority of His Bride: The Holy Roman Catholic Church.
