The five thousand fully satisfied from being fed now begin to desire to make Jesus king (John 6). When Jesus perceives their intention toward Him, He dismisses Himself from their presence.
Jesus knew His purpose. This time on earth served the purpose of providing salvation for us. Jesus kept His sights on what He was called to do. He knew in the right time, His day would come to rule as king, and that time had not yet arrived. We still wait for that day.
Do we know our purpose? Do we know how to keep our focus on what the Lord calls us to do today? Let's guard against jumping ship to the next best thing and therefore miss out on God's perfect timing for all things right now.
