1 Corinthians 15:15-17

Young's Literal Translation

¹⁵ and we also are found false witnesses of God, because we did testify of God that He raised up the Christ, whom He did not raise if then dead persons do not rise;

¹⁶ for if dead persons do not rise, neither hath Christ risen,

¹⁷ and if Christ hath not risen, vain is your faith, ye are yet in your sins;
