Why is the concept of Christ as our champion important for Christians?

The understanding of Christ as our champion parallels the story of David and Goliath, where David fought on behalf of Israel. In the same way, Christ fought for His people against the giants of sin, death, and the law. His victorious suffering secured redemption for the elect by paying the penalty for their sins. This concept is crucial for Christians because it establishes that our salvation is rooted in Christ’s completed work, assuring us that He represents us before the Father and that we are safe in His victory.
