Acts 27:25

Wherefore, sirs, be of good cheer
Which he repeats with more fervency and earnestness, there being so much reason for it:

for I believe God, that it shall be even as it was told me:
true faith lays hold and, settles upon the word and promises of God; and the true believer, knowing his power and faithfulness, firmly persuaded that there shall be a performance of what is said by him, with respect to matter, manner, and circumstances. Whatever God has told his people of, or has promised unto them, shall be performed, whether with respect to things temporal; that they shall not want any good thing; that all their afflictions shall be for their good; that they shall be supported under them, and at last brought out of them: or whether with respect to spiritual things; whatever he has said concerning himself, that he will be their God, will continue to love them, will not leave them, nor forsake them, will guide and protect them, will supply all their need, and give them grace here, and glory hereafter; and whatever he has said concerning his Son, that he is their Saviour and Redeemer, that they are justified by his righteousness, pardoned through his blood, and shall be saved in him with an everlasting salvation; and whatever he has said concerning his Spirit, that he shall enlighten them more and more, carry on his good work in them, and finish it, shall be their comforter and their guide, shall strengthen them in their inward man, and work them up for that selfsame thing, eternal glory: and likewise, whatever he has said concerning the prosperity and happiness of the churches in the latter day; even all those glorious things spoken of the city of God; and which relate both to the spiritual and personal reign of Christ. Faith takes all this at his word, and firmly believes it shall be as he has said: and it has good grounds and reasons for acting in this manner; from the veracity, faithfulness, and power of God, who has promised; and from the nature of the promises themselves, which are unconditional, immutable, all in Christ, and yea and amen in him, and not one of them has ever failed: and such a believing frame of soul greatly encourages cheerfulness of spirit, and produces it: a believer is cheerful himself, as he has reason to be; he is filled with joy and peace in believing, yea, with a joy unspeakable, and full of glory; and he makes all about him cheerful; he comforts others with the same comforts he has been comforted of God; and however, he exhorts, after his own example, to believe, and be of good cheer; see ( 2 Chronicles 20:20 ) .
