How do we know that Jesus is our champion in the spiritual battle?

The affirmation that Jesus is our champion is rooted in His sacrificial victory over sin and death. Scripture teaches that Christ undertook the ultimate battle not with physical weapons but through His death on the cross, which was essential for our redemption. He faced our greatest adversary, Satan, and emerged victorious by defeating sin, which brings forth death. The resurrection of Christ substantiates this victory; because He lives, we, too, can have life through Him. This truth is underscored in Romans 8:31-39, where we read that nothing can separate us from the love of God in Christ Jesus, assuring us that He is indeed our stronghold and champion in the spiritual realm.
