How do we know that Jesus came to redeem us?

The sermon illustrates that Christ's coming was not merely a suggestion but a fulfillment of God's covenant promises. In Luke 1:70-72, it states that Jesus came to perform the mercy promised to our fathers and to remember His holy covenant. This covenant was established when God swore by Himself to Abraham, guaranteeing that salvation was secured through Christ's work, as emphasized in Romans 4 and Galatians 3. Thus, His coming is a concrete act of divine fulfillment, demonstrating that He indeed came to save His people.
