Matthew Henry Commentary Mark 16:19-20

"So then the Lord Jesus, after he had spoken unto them, was received up into heaven, and sat down at the right hand of God. And they went forth, and preached everywhere, the Lord working with them, and confirming the word by the signs that followed. Amen." — Mark 16:19-20 (ASV)

After the Lord had spoken, He went up into heaven. Sitting is a posture of rest, for He had finished His work; it is also a posture of rule, for He took possession of His kingdom. He sat at the right hand of God, which denotes His sovereign dignity and universal power. Whatever God does concerning us, gives to us, or accepts from us, it is by His Son.

Now He is glorified with the glory He had before the world. The apostles went out and preached everywhere, far and near. Although the doctrine they preached was spiritual and heavenly, and directly contrary to the spirit and temper of the world; although it met with much opposition and was wholly destitute of all worldly supports and advantages; yet, in a few years, the sound went out to the ends of the earth.

Christ's ministers do not now need to work miracles to prove their message. The Scriptures are proved to be of divine origin, and this renders those without excuse who reject or neglect them. The effects of the gospel, when faithfully preached and truly believed, in changing the tempers and characters of mankind, form a constant proof—a miraculous proof—that the gospel is the power of God unto salvation, of all who believe.
