"During His ministry, Jesus had kept constantly before the disciples the fact that they were to be one with Him in His work for the recovery of the world from the slavery of sin. When He sent forth the Twelve and afterward the Seventy, to proclaim the kingdom of God, He was teaching them their duty to impart to others what He had made known to them. In all His work He was training them for individual labor, to be extended as their numbers increased, and eventually to reach to the uttermost parts of the earth. The last lesson He gave His followers was that they held in trust for the world the glad tidings of salvation. AA 32.1"
"Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:"

"When the time came for Christ to ascend to His Father, He led the disciples out as far as Bethany. Here He paused, and they gathered about Him.

AA 32.2"
"And it came to pass, while he blessed them, he was parted from them, and carried up into heaven."

"While the disciples were gazing upward to catch the last glimpse of their ascending Lord, He was received into the rejoicing ranks of heavenly angels. As these angels escorted Him to the courts above, they sang in triumph, “Sing unto God, ye kingdoms of the earth; O sing praises unto the Lord, to Him that rideth upon the heavens of heavens.... Ascribe ye strength unto God: His excellency is over Israel, and His strength is in the heavens.” Psalm 68:32-34 , margin. AA 32.3"
