But God will redeem my soul from the power of the grave: for he shall receive me. Selah. (Psalms 49:15)
Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen: To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God: (Acts 1:2-3)
Crushed by despondency, grief, and despair, the disciples met together in the upper chamber, and closed and fastened the doors, fearing that the fate of their beloved Teacher might be theirs. It was here that the Saviour, after His resurrection, appeared to them.
For forty days Christ remained on the earth, preparing the disciples for the work before them and explaining that which heretofore they had been unable to comprehend. He spoke of the prophecies concerning His advent, His rejection by the Jews, and His death, showing that every specification of these prophecies had been fulfilled. He told them that they were to regard this fulfillment of prophecy as an assurance of the power that would attend them in their future labors. "Then opened He their understanding," we read, "that they might understand the Scriptures, and said unto them, Thus it is written, and thus it behooved Christ to suffer, and to rise from the dead the third day: and that repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem."
And He added, "Ye are witnesses of these things." Luke 24:45-48. During these days that Christ spent with His disciples, they gained a new experience. As they heard their beloved Master explaining the Scriptures in the light of all that had happened, their faith in Him was fully established. They reached the place where they could say, "I know whom I have believed." 2 Timothy 1:12. They began to realize the nature and extent of their work, to see that they were to proclaim to the world the truths entrusted to them. The events of Christ's life, His death and resurrection, the prophecies pointing to these events, the mysteries of the plan of salvation, the power of Jesus for the remission of sins--to all these things they had been witnesses, and they were to make them known to the world. They were to proclaim the gospel of peace and salvation through repentance and the power of the Saviour
