How do we know the truth of God's faithfulness?

The faithfulness of God is a foundational attribute that reassures believers of His reliability. In 2 Timothy 2:13, we see that even if we are unfaithful, He remains faithful because denying Himself is impossible. This means that God's promises are steadfast and true, providing certainty for those who trust in Him. The psalmist in Psalm 119:90 also asserts that God's faithfulness endures to all generations, affirming that He has been and will always be reliable in His word and actions.
