36 Simon Peter said to Him, “Lord, where are You going?” Jesus answered him, “Where I am going you cannot follow Me now, but you shall follow Me afterward.” 37 Peter said to Him, “Lord, why can I not follow You now? I will lay down my life for Your sake.” 38 Jesus answered him, “Will you lay down your life for My sake? Most assuredly, I say to you, the rooster shall not crow till you have denied Me three times.” (John 13:36–38, NKJV)
Jesus was headed for Golgotha (the place of a skull), there to die a disgraceful death for the sins of the world, and afterward to enter His glory (John 17:4-5). Peter would follow Jesus in life, and in his death he would glorify God (John 21:18-19). But for now, as Jesus was on His way to Golgotha, Peter’s overconfidence would be betrayed by fear and doubt, leading him to deny even knowing Jesus (John 18:15-18, 25-27). And so, we learn to be careful not to become self-righteous and arrogant in our faith. We learn of God’s amazing forgiveness, for Peter went on to be a great apostle of Christ. And, we learn that even when we grievously sin, the Lord will receive us back and use us for His purposes. So, let us follow Jesus in faithful obedience, nothing doubting. He will lead us to heaven, the place He has already gone.
