“The promise of Christ’s second coming was ever to be kept fresh in the minds of His disciples. The same Jesus whom they had seen ascending into heaven, would come again, to take to Himself those who here below give themselves to His service. The same voice that had said to them, “Lo, I am with you alway, even unto the end,” would bid them welcome to His presence in the heavenly kingdom.”
Acts of the Apostles p. 33
