7 and he said unto them, 'It is not yours to know times or seasons that the Father did appoint in His own authority; 8 but ye shall receive power at the coming of the Holy Spirit upon you, and ye shall be witnesses to me both in Jerusalem, and in all Judea, and Samaria, and unto the end of the earth.' 9 And these things having said—they beholding—he was taken up, and a cloud did receive him up from their sight; 10 and as they were looking stedfastly to the heaven in his going on, then, lo, two men stood by them in white apparel, 11 who also said, 'Men, Galileans, why do ye stand gazing into the heaven? this Jesus who was received up from you into the heaven, shall so come in what manner ye saw him going on to the heaven.'
Matthew Henry's Commentary on Acts 1:7-11
Commentary on Acts 1:6-11
(Read Acts 1:6-11)
They were earnest in asking about that which their Master never had directed or encouraged them to seek. Our Lord knew that his ascension and the teaching of the Holy Spirit would soon end these expectations, and therefore only gave them a rebuke; but it is a caution to his church in all ages, to take heed of a desire of forbidden knowledge. He had given his disciples instructions for the discharge of their duty, both before his death and since his resurrection, and this knowledge is enough for a Christian. It is enough that He has engaged to give believers strength equal to their trials and services; that under the influence of the Holy Spirit they may, in one way or other, be witnesses for Christ on earth, while in heaven he manages their concerns with perfect wisdom, truth, and love. When we stand gazing and trifling, the thoughts of our Master's second coming should quicken and awaken us: when we stand gazing and trembling, they should comfort and encourage us. May our expectation of it be stedfast and joyful, giving diligence to be found of him blameless.
