2. As we have seen in our former lectures, that faith was the principle of action and of power in all intelligent beings, both in heaven and on earth, it will not be expected that we shall, in a lecture of this description, attempt to unfold all its effects; neither is it necessary to our purpose so to do; for it would embrace all things in heaven and on earth, and encompass all the creations of God, with all their endless varieties: for no world has yet been framed that was not framed by faith; neither has there been an intelligent being on any of God's creations who did not get there by reason of faith, as it existed in himself or in some other being; nor has there been a change or a revolution in any of the creatures of God, but it has been effected by faith: neither will there be a change or a revolution unless it is effected in the same way, in any of the vast creations of the Almighty; for it is by faith that the Deity works. 3. Let us here offer some explanation in relation to faith, that our meaning may be clearly comprehended: We ask, then, what are we to understand by a man's working by faith? We answer: We understand that when a man works by faith he works by mental exertion instead of physical force: it is by words instead of exerting his physical powers, with which every being works when he works by faith--God said, Let there be light, and there was light--Joshua spake and the great lights which God had created stood still--Elijah commanded, and the heavens were stayed for the space of three years and six months, so that it did not rain: he again commanded and the heavens gave forth rain--all this was done by faith; and the Saviour says, If you have faith as a grain of mustard seed, say to this mountain, remove, and it will remove; or say to that sycamine tree, Be ye plucked up and planted in the midst of the sea, and it shall obey you. Faith, then, works by words; and with these its mightiest works have been, and will be, performed. 4. It surely will not be required of us to prove, that this is the principle upon which all eternity has acted and will act; for every reflecting mind must know, that it is by reason of this power that all the hosts of heaven perform their works of wonder, majesty, and glory: Angels move from place to place by virtue of this power--it is by reason of it that they are enabled to descend from heaven to earth; and were it not for the power of faith they never could be ministering spirits to them who should be heirs of salvation, neither could they act as heavenly messengers; for they would be destitute of the power necessary to enable them to do the will of God.
