Jesus extended an invitation to his disciples to “Come follow me.” He meant it. He literally invited them to leave their nets, their tax stall, their current job and become his followers. They spent time with him learning about the kingdom of God and doing the work along with Jesus. I’m sure that it was an amazing 3+ years that ended all to soon.
Yet even the disciples experienced the presence of Jesus after he left them through the person of the Holy Spirit. Jesus promised to be with them always and so they continued to follow Jesus by the power of the Holy Spirit. They changed their world because they continued to follow Christ.
You and I are at the same place today. Jesus is not physically with us so that we can touch him or hear his teaching directly from his mouth. But here we are following Jesus by the power of the Holy Spirit just like the early believers. God has not changed his tactics nor his desire to see his followers change their world. Christ is in you and he is the hope of glory.
What should we do then? We should follow Jesus like the disciples did. We listen to what the Spirit is saying to us and go forward in faith believing that God will use us to change our world. It is an awesome privilege to follow Jesus.
