How do we know the greatness of salvation is true?

The greatness of salvation originates in the love and wisdom of God, which are unchanging and eternal. As the sermon outlines, salvation does not begin with human action but with God's sovereign choice to set His love upon a specific people. The fulfillment of covenantal obligations by Jesus Christ, our mediator, assures us that this salvation is not only profound in origin but also perfect in its execution on the cross. It is the resurgence of God's promise that underscores the absolute truth of salvation, cemented in Christ's sacrifice, which provides security for believers as affirmed in Ephesians 1:4-5.
