The disciples loved Jesus Christ to the limit of their natural capacity, but they did not fully understand His purpose. In the Garden of Gethsemane they slept as a result of their own sorrow, and at the end of three years of the closest and most intimate relationship of their lives they “all…forsook Him and fled” (Matthew 26:56).

“They were all filled with the Holy Spirit…” (Acts 2:4). “They” refers to the same people, but something wonderful has happened between these two events— our Lord’s death, resurrection, and ascension— and the disciples have now been invaded and “filled with the Holy Spirit.” Our Lord had said, “You shall receive power when the Holy Spirit has come upon you…” (Acts 1:8). This meant that they learned to watch with Him the rest of their lives.
