How do we know that Jesus acted without the fear of death?

In John 10:17-18, Jesus asserts His authority over life and death, illustrating that He was not motivated by fear of death. He explicitly claims that He lays down His life voluntarily and has the power to take it back again. This self-assuredness underlines the sovereignty of Christ and assures believers that He is the source of eternal life. When we see Jesus actively engaging with His mission even in the face of threats to His life, it teaches us to similarly trust in God's sovereignty over our lives and the assurance of resurrection, as found in John 11:25, where He affirms, 'I am the resurrection and the life'. His actions thus stand as a model for us, pointing us to rely not on our circumstances but on the promises of God.
