How does the name of Christ give power to believers?

The name of Christ carries an unparalleled power that gives credence to every promise made to believers. As noted in the sermon, when statements are made 'in Christ' or 'through Christ', they are solidified, becoming immutable truths. This power stems from Christ's authority as the name above every name, which assures believers that their salvation and God's promises are secure. In Ephesians 1, various spiritual blessings are highlighted, and all are affirmed through Christ's name, ensuring they are not merely hopeful assertions but guaranteed realities. Therefore, the name of Christ not only signifies His identity but confirms the reliability and strength of the gospel.
