How do we know God is faithful despite human unbelief?

Paul firmly asserts that human disbelief does not cancel out God's faithfulness. Instead, he proclaims, 'Let God be true, but every man a liar' (Romans 3:4). The promises made to Israel have always been fulfilled, highlighting that God's word and judgment are reliable. Even when faced with the hard-heartedness of men, God's purpose stands firm. This faithfulness is evident in how God draws His chosen ones irresistibly to faith in Christ, showcasing that it is by God's will and action that we come to believe.
