The presence of Christ with the Christian has numerous benefits. Christ is like the Good Shepherd, guiding us through life, and He is sovereign over everything. This realization gives us a deep peace. It is most significant that when Christ met His disciples after He rose from the dead, He often gave them greetings of peace (Luke 24:36; John 20:19, 21,26). This peace touches every area of life that could trouble us. We are freed from a troubled conscience that could bother us with guilt feelings over the past. We have courage to face the challenges of the present because Jesus, who is sovereign over all things, is with us. We are not anxious about the future. So the peace of Christ touches our attitude to the past, the present, and the future. It is a peace completely different from the peace the world gives (John 14:27), for it is not dependent on circumstances, but on Him, and He is "the same yesterday and today and forever" (Hebrews 13:8).
