Circa 2000 BC: And Abram believed the Lord, and the Lord counted him as righteous because of his faith. Genesis 15:6 NLT

Circa 57 AD: Now to the one who works, the wages are not credited as a favor, but as what is due. But to the one who does not work, but believes in Him who justifies the ungodly, his faith is credited as righteousness. Romans 4:3-5 NASB

Circa Futurum: Now I saw a new heaven and a new earth, for the first heaven and the first earth had passed away…. And I heard a loud voice from heaven saying, ‘Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people….’ Then He who sat on the throne said, ‘Behold, I make all things new.’” Revelation 21:1, 3, 5 NKJV

Across all of redemptive history, God’s way of declaring sinners righteous has never changed: salvation is by God’s grace, received through faith, and never earned by human works.
