God's promises in Christ are true because they are fulfilled through His faithful character and actions as seen in Scripture.
God's promises in Christ can be fully trusted as they are grounded in His faithful and immutable character. In Deuteronomy 7:9, it affirms that the Lord our God is a faithful God, keeping His covenant and mercy with those who love Him. This reliability is further reflected in the New Testament where the Apostle Paul emphasizes that God is faithful, by whom we were called unto the fellowship of His Son, Jesus Christ our Lord. The surety of God's promises does not rely on human faithfulness but on His sovereign will and purpose. For instance, in John 6:37, Jesus asserts, 'All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out,' demonstrating that God's calling is effectual and guarantees that none whom He has chosen will be left out.
The fulfillment of prophecy concerning Christ's coming, His incarnation, and His atoning work on the cross further show that God's word is reliable. The steadfastness of His word assures believers that the promises of salvation, grace, and eternal life are not mere possibilities but certainties for those whom He has redeemed. Thus, the faithfulness of God confirms the truth of His promises, which remain worthy of all acceptation.
