What does it mean to declare Christ as all in salvation?

To declare Christ as all in salvation means recognizing that He alone is responsible for our justification and sanctification. Acts 4:12 indicates that there is no other name under heaven by which we must be saved, emphasizing His unique role in providing salvation. It's essential for believers to understand that Christ embodies the entirety of redemption; He is our representative before God, and His righteousness is credited to us. This declaration reinforces the idea that salvation is not a collaborative effort between God and man but a work solely accomplished by Christ's finished sacrifice.
