The first followers to witness Jesus' resurrection from the dead were the women who ministered to Him. They experienced an angelic announcement to go and tell the other disciples, and then as they went in obedience, they had a personal encounter with Jesus! Think about that! As they were traveling back from the empty tomb to the place where the disciples were hidden away in fear, Jesus met them on the road. Jesus encouraged these women to continue believing and acting in obedience. He knew there would be doubts from some of the twelve (Thomas), but they were to press forward in faith and share the good news. Sadly, the disciples missed this divine opportunity that the women experienced.
Matthew ends with the disciples returning to Galilee and experiencing their own personal encounter with Jesus. Even though there were some doubts, they accepted His mandate to go into all the known world surrounding Israel and share the Gospel with all nations. And the disciples (including the Apostle Paul) did just that. By the time Judgment Day came in 70 AD, the disciples and apostles had completed their task of delivering the message of Jesus and the New Kingdom, just as the Lord directed!
Today, we the church, the body of Christ, are to continue that mandate - to share the good news of the Gospel and advance the Kingdom!
