Complete Romans 3:4: 'Let God be true and every man a ___.'

Answer: Liar

Asking whether unbelief nullifies God's faithfulness, Paul answers, "Certainly not! Let God be true and every man a liar."

“What if some did not have faith? Will their lack of faith nullify God’s faithfulness? Certainly not! Let God be true and every man a liar. As it is written: “So that You may be proved right when You speak and victorious when You judge.””— Romans 3:3-4 (BSB)
