How do we know God's promises of salvation are true?

We know God's promises of salvation are true through His faithfulness in fulfilling the prophecies throughout Scripture. In Genesis 49:10, for instance, Jacob prophesies the coming of Shiloh, referring to Jesus Christ, whose arrival established the ultimate fulfillment of salvation. God's immutable nature assures us that His promises never fail, as He remains faithful to His Word and His covenant with His people. The continuous testimony of Scripture, alongside the experiences of believers throughout history who have witnessed God's salvific work in their lives, reinforces our conviction in the truth of these promises.
