John 14:1 - Coke's Commentary on the Holy Bible

Let not your heart be troubled:— Jesus not only forewarned his disciples of the great trial that was coming upon them, and commanded them to arm themselves against it, (see Luke 22:35-38.) but he spoke a long discourse, wherein he animated them to sustain that trial manfully, and comforted them under the dismal apprehensions which it might raise in them. They were to see Him crucified whom they had acknowledged as the Messiah; wherefore having been always accustomed to consider temporal dominion as the characteristic of their deliverer, and great worldly prosperity as the privilege of his subjects; the death of their Master, and the persecutions befalling themselves, could not fail to give a violent shock to their faith. But, that the force of these blows might be weakened, our Lord foretold his own sufferings, and thereby made it evident, that he voluntarily submitted to them. Withal, to reconcile their minds to the thoughts of his sufferings, he distinctly explained the end of them in this discourse. Let not your heart be troubled, &c. "Be not discomposed with the thoughts of those temptations which are to come upon you. As you believe in God, in a general point of view, as the almighty preserver and governor of the world, who is able to deliver you out of all your distresses; believe also in me; who am not only sent by God, and appointed governor and judge of the world, but am myself God over all, blessed for ever; and therefore can both protect you from evil, and reward you plentifully, for whatever losses you may sustain on my account." The Greek of the last clause may be rendered, Believe in God, and believe also in me; and it appears most natural to render the word πιστευετε, alike in both places; and it is certain that an exhortation to faith upon God in Christ, would be very seasonable, considering how weak and defective their faith was. See John 14:9.
