How do we know that God's promises will come to pass?

God's faithfulness is one of His core attributes, ensuring that His promises will not fail. Throughout the entire narrative of Scripture, we see the faithfulness of God highlighted in His covenants. The assurance that 'underneath are the everlasting arms' (Deuteronomy 33:27) reinforces the hope within the believer that God's promises are securely held. Furthermore, the character of God, which is unchanging and eternal, gives us confidence that His word will always accomplish what it was intended to achieve, as stated in Isaiah 55:11.
