“Then the disciples went out and proclaimed the good news everywhere, while the Lord worked with them and confirmed his word by the signs that accompanied it.”  (Mark 16:20)

Before His Ascension, Jesus said to His Disciples, “Go into all the world and preach the good news to the whole creation.”  So the disciples must first leave their comfort zones and travel into strange territories.  Naturally, their only sense of security would have come from Jesus, and Jesus alone.

When the disciples preached during Jesus’ time, they were used to going out and preach in pairs.  After Jesus’ Ascension, the disciples continued to preach and witness in groups.  By working in teams, they witnessed the importance of love.  At the same time, they made sure that Jesus was among them. “Where two or three are gathered together in my name, there am I in the midst of them.”

More importantly, “the Lord worked with them”.  Acts recorded quite a few anecdotes of Peter and Paul preaching in different regions, where they healed, and even resurrected people in Jesus’ name.  The disciples have deep faith in Jesus, who said, “Without me, you can do nothing.”
