At the meeting on a mountain in Galilee, all the believers who could be called together were assembled. Of this meeting Christ Himself, before His death, had designed the time and place....
At the time appointed, about five hundred believers were collected in little knots on the mountainside, eager to learn all that could be learned from those who had seen Christ since His resurrection. From group to group the disciples passed, telling all they had seen and heard of Jesus, and reasoning from the Scriptures as He had done with them. Thomas recounted the story of his unbelief, and told how his doubts had been swept away. Suddenly Jesus stood among them. No one could tell whence or how He came. Many who were present had never before seen Him; but in His hands and feet they beheld the marks of the crucifixion; His countenance was as the face of God, and when they saw Him, they worshiped Him.
But some doubted. So it will always be. There are those who find it hard to exercise faith, and they place themselves on the doubting side. These lose much because of their unbelief.
This was the only interview that Jesus had with many of the believers after His resurrection. He came and spoke to them saying, “All power is given unto me in heaven and in earth.” The disciples had worshiped Him before He spoke, but His words, falling from lips that had been closed in death, thrilled them with peculiar power. He was now the risen Saviour. Many of them had seen Him exercise His power in healing the sick and controlling satanic agencies. They believed that He possessed power to set up His kingdom at Jerusalem, power to quell all opposition, power over the elements of nature. He had stilled the angry waters; He had walked upon the white-crested billows; He had raised the dead to life. Now He declared that “all power” was given to Him. His words carried the minds of His hearers above earthly and temporal things to the heavenly and eternal. They were lifted to the highest conception of His dignity and glory.
Christ’s words on the mountainside were the announcement that His sacrifice in behalf of man was full and complete. The conditions of the atonement had been fulfilled; the work for which He came to this world had been accomplished. He was on His way to the throne of God, to be honored by angels, principalities, and powers. He had entered upon His mediatorial work. Clothed with boundless authority, He gave His commission to the disciples: “Go ye therefore, and teach all nations” (The Desire of Ages, 818, 819). LHU 322
Our devotional exercises should not consist wholly in asking and receiving. Let us not be always thinking of our wants and never of the benefits we receive. We do not pray any too much, but we are too sparing of giving thanks. Pr 287
