14 Afterwards, as they are reclining (at meat), he was manifested to the eleven, and did reproach their unbelief and stiffness of heart, because they believed not those having seen him being raised; 15 and he said to them, 'Having gone to all the world, proclaim the good news to all the creation; 16 he who hath believed, and hath been baptized, shall be saved; and he who hath not believed, shall be condemned. 17 'And signs shall accompany those believing these things; in my name demons they shall cast out; with new tongues they shall speak; 18 serpents they shall take up; and if any deadly thing they may drink, it shall not hurt them; on the ailing they shall lay hands, and they shall be well.'
19 The Lord, then, indeed, after speaking to them, was received up to the heaven, and sat on the right hand of God;

The evidences of the truth of the gospel are so full, that those who receive it not, may justly be upbraided with their unbelief. Our blessed Lord renewed his choice of the eleven as his apostles, and commissioned them to go into all the world, to preach his gospel to every creature. Only he that is a true Christian shall be saved through Christ. Simon Magus professed to believe, and was baptized, yet he was declared to be in the bonds of iniquity: see his history in Acts 8:13-25. Doubtless this is a solemn declaration of that true faith which receives Christ in all his characters and offices, and for all the purposes of salvation, and which produces its right effect on the heart and life; not a mere assent, which is a dead faith, and cannot profit. The commission of Christ's ministers extends to every creature throughout the world, and the declarations of the gospel contain not only truths, encouragements, and precepts, but also most awful warnings. Observe what power the apostles should be endued with, for confirming the doctrine they were to preach. These were miracles to confirm the truth of the gospel, and means of spreading the gospel among nations that had not heard it.
Commentary on Mark 16:19-20
(Read Mark 16:19-20)
After the Lord had spoken he went up into heaven. Sitting is a posture of rest, he had finished his work; and a posture of rule, 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 forth, and preached every where, far and near. Though the doctrine they preached was spiritual and heavenly, and directly contrary to the spirit and temper of the world; though it met with much opposition, and was wholly destitute of all worldly supports and advantages; yet in a few years the sound went forth unto 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.
