After claiming to be the ‘Good Shepherd’ who loves and dies for His sheep, Jesus went on to speak about the eternal security of His sheep. Because He is God and by His death saves His sheep completely, he can say that none of His sheep will be lost. Such truths are of great comfort to the believer, but also should cause discomfort to those who do not believe. If there is no salvation outside of Jesus, then no man or woman can have any hope of eternal security without belonging to Him.
