What kind of ministry did Jesus accomplish, which the disciples were to continue?
Jesus accomplished a ministry marked by signs and miracles beyond human understanding during three years. The disciples were to continue that same ministry, empowered by the Holy Spirit on Pentecost, giving Jewish believers power to carry on the miraculous work Christ had performed.
Les explains that Jesus had been accomplishing a ministry for three years that was characterized by signs and miracles beyond human understanding. After His resurrection, the disciples were still thinking about the kingdom and ruling the twelve tribes of Israel. Jesus did not rebuke them, but told them it was not for them to know the times or seasons. In the interim, they would receive power when the Holy Spirit came at Pentecost, and that power was to enable these Jewish believers to continue the same ministry Christ had accomplished. These men were to have that kind of power.
But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
