And you are witnesses of these things.

“But if those things which Christ foretold are already receiving their accomplishment, and His word is perceived by a seeing faith to be living and effectual throughout the whole world; it is time for men not to be unbelieving towards Him who uttered that word. For it is necessary that He should live a divine life, whose living works are shewn to be agreeable to His words; and these indeed have been fulfilled by the ministry of the Apostles. Hence He adds, But ye are witnesses of these things, &c. that is, of My death and resurrection.”

“And they worshipped him,.... Not with a civil worship, as he was sometimes worshipped by men, in the days of his flesh, who, though they took him for some extraordinary person, knew him not to be the Son of God; but with religious worship as God: for by his resurrection from the dead, Christ was declared to be the Son of God, and both by that, and by his going to his Father, his ascension to heaven, the disciples were more confirmed in his proper deity, and divine sonship; and therefore worshipped him as God; by calling upon his name, ascribing blessings and honour, and glory, to him; by making him the object of their reverence and fear; and by trusting in him; and by doing every religious act in his name, and which they ever after continued to do: and returned to Jerusalem: as they were ordered, where they were to tarry and wait for the pouring down of the Spirit: and this they did with great joy; for though their Lord was parted from them, and was gone to heaven, this did not cause sorrow, as did his death, but, on the contrary, joy, even great joy; partly because of the glory he was entered into, and possessed of; and partly on account of what he was gone to do for them; to appear in the presence of God for them, to make intercession for them, to take possession of heaven in their name, and to prepare a place for them, as well as to receive gifts for them; and now they return to Jerusalem with great cheerfulness, in full hope and expectation, yea, assurance of faith, that they should shortly receive the promise of the Father.”

“Ye are witnesses of these things - He gave them a full commission to proclaim these glad tidings of peace and salvation to a lost world. The disciples were witnesses not only that Christ had suffered and rose again from the dead; but also that he opens the understanding by the inspiration of his Spirit, that he gives repentance, that he pardons sin, and purifies from all unrighteousness, and that he is not willing that any should perish, but that all should come unto the knowledge of the truth and be saved. And these are the things of which their successors in the Gospel ministry must bear witness. As far as a man steadily and affectionately proclaims these doctrines, so far God will bless his labor to the salvation of those who hear him. But no man can with any propriety bear witness of that grace that saves the soul, whose own soul is not saved by that grace.”
