How do we know God's promises are secure for His people?

The assurance of God’s promises stems from His unchanging character outlined in Malachi 3:6, which states, 'I am the Lord, I change not.' This immutability signifies that God's commitments to His people are not subject to alteration or failure. Scripture repeatedly affirms that those who are in Christ are preserved through His everlasting love. As Romans asserts, nothing can separate us from the love of God in Christ Jesus. Therefore, believers can trust wholeheartedly that God's covenant promises will endure forever, affirming our security in Him as His chosen people—'the sons of Jacob' referenced in the text.
