The third commandment was how they would demonstrate to the world that they were different (John 13:31-35). Following this command would be the glue that would hold them together through constant attack and through incredibly destructive persecution. They must love each other. Not the kind of love that is wishy-washy or that makes pleasant toe-tapping tunes on the radio. But the kind of love that secures someone through the most incredibly difficult circumstances--the love that frees us from the fear of persecution (1 John 4:18). God could have abandoned us all, and had several opportunities to do just that (see Genesis chapter 6). But instead, He always had a remnant and a plan for the redemption of those devoted to Him (Romans 11:2-5).
The fourth command that Jesus gave that night was for the disciples there, and for those of us who follow in their footsteps, to remember His sacrifice (Luke 22:14-20). This was the reality of their redemption--the Paschal lamb, now in the flesh (1 Corinthians 5:7), giving His life for all who would trust in Him (Romans 10:9). “Do this in remembrance of me!” (Luke 22:19). When times are tough, when the enemy is attacking, when we lose those closest to us through cancer or some incredible tragedy, when we are fired from our job after standing up for what we believe, what memory would keep us on point and mindful of what Jesus had done? We needed to remember His sacrifice--not simply wafer and grape juice, or bread and wine--but a sinless Life, from Eternal Glory, embodied now the form of His disgraced creation, standing in for us who really deserved this punishment!
By this time tomorrow, He would give His life for them--for us! Later that night He promised that He was going to prepare a place for us (John 14:2). He said that He would be with us always (Matthew 28:20). He said that He would not abandon or forsake us (Hebrews 13:5). But we must follow the commands of our Commander-in-Chief. We must stay focused on the task at hand, and not let the distractions of this world and the rituals of our church experience become trite or become a parody of what actually happened in that upper room.
