44 And he said unto them, These are my words which I spake unto you, while I was yet with you, that all things must needs be fulfilled, which are written in the law of Moses, and the prophets, and the psalms, concerning me.45 Then opened he their mind, that they might understand the scriptures; 46 and he said unto them, Thus it is written, that the Christ should suffer, and rise again from the dead the third day; 47 and that repentance and remission of sins should be preached in his name unto all the nations, beginning from Jerusalem.48 Ye are witnesses of these things.49 And behold, I send forth the promise of my Father upon you: but tarry ye in the city, until ye be clothed with power from on high.

It need not be supposed that the last words of Jesus as recorded by Luke were spoken on the day of the resurrection or at any one time or place. They more probably indicate the general substance of those teachings which are given by the risen Christ to his disciples during the forty days between his resurrection and his ascension.

They are luminous with truths which are needed by the disciples of Christ to-day. Among them are such facts as these: The Scriptures contain authoritative messages concerning Christ; these messages can be understood only by those who believe in Christ and are guided by him; the essential truths concerning Christ center in the facts of his death and resurrection; in virtue of the salvation thus secured, repentance and forgiveness of sins can be preached; this salvation is to be proclaimed in all the world; the followers of Christ are the messengers by whom this good news is to be made known; the power for such proclamation is imparted by the Spirit of Christ who was manifested in new power on the Day of Pentecost, and who is now an abiding Presence and a source of limitless strength to all who seek to do the will of Christ and to glorify his name.
