God's word is reliable because it is unchanging and fulfilled, as demonstrated in Luke 1:13-14, where the prophecy about John the Baptist is realized.
The reliability of God's word is affirmed in Scripture through the consistent fulfillment of His promises. In Luke 1:13-14, the angel Gabriel conveyed God’s specific instructions to Zacharias regarding the birth of his son, John. The subsequent events demonstrate that what God said would occur came to pass without fail. The assurance that God's word is settled forever in heaven underscores its trustworthiness. This is further supported by the fact that God does not change; thus, His word remains true and reliable across all generations. Believers can take comfort in the certainty that when God promises, He will act according to His word, providing a strong foundation for faith.
