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 Ac 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.
