This union of our souls and bodies, is the reason both why we have so little and so much power over ourselves. It is owing to this, that we have so little power over our souls: for as we cannot prevent the effects of external objects upon our bodies; as we cannot command outward causes; so we cannot always command the inward state of our minds; because, as outward objects act upon our bodies without our leave, so our bodies act upon our minds by the laws of the union vital. And thus you see it is owing to this union, that we have so _little_ power over ourselves.
On the other hand, it is owing to this union, that we have so _much_ power over ourselves. For as our souls in a great measure depend upon our bodies; and as we have great power over these; as we can mortify our bodies, and remove ourselves from objects that inflame our passions; so we have a great power over the _inward_ state of our souls. Again, as the outward acts of reading, praying, singing, and the like, have an effect upon the soul; so by being masters of these outward, bodily actions, we have great power over the inward state of the heart.
And thus it is owing to this union, that we have so much power over ourselves.
Now from this you may see the benefit of singing psalms, and of all the outward acts of religion; for if the body has so much power over the soul, all such bodily actions as affect the soul, are of great weight in religion, because they are proper to support that _spirit_, which is the true worship of God.
21. This doctrine may be easily carried too far; for by calling in too many outward means of worship, it may degenerate into superstition. But some have fallen into the contrary extreme. Because religion is justly placed in the heart, they renounce vocal prayer, and other outward acts of worship, and resolve all religion into a _quietism_, or _mystic_ intercourse with God in silence.
But since we are neither _all soul_, nor _all body_; seeing none of our actions are either separately of the soul, or separately of the body; if we would truly prostrate ourselves before God, we must use our bodies to postures of lowliness. If we desire true fervours of devotion, we must make prayer the frequent labour of our lips. If we would feel inward joy and delight in God, we must practise all the outward acts of it, and make our voices call upon our hearts.
Now therefore, you may plainly see the reason of _singing of psalms_; it is because outward actions are necessary to support inward tempers.
22. I have been the longer upon this head, because of its importance to true religion. For there is no state of mind so excellent, as that of _thankfulness_ to God; and consequently, nothing is of more importance than that which exercises and improves this habit of mind.
*An _uneasy_, _complaining_ spirit, which is sometimes the spirit of those that seem careful of religion, is yet of all tempers the most contrary to religion; for it disowns that God which it pretends to adore. For he sufficiently disowns God, who does not adore him as a being of infinite goodness.
*If a man does not believe that all the world is as God’s family, where nothing happens by chance, but all is guided and directed by the care and providence of a being that is all love and goodness to all his creatures; if a man does not believe this from his heart, he cannot be said to believe in God. And yet he that has this faith, has faith enough to be always thankful to God. For he that believes every thing happens to him for the _best_, cannot complain for the want of something that is _better_.
If therefore you live in murmurings and complaints, it is not because you are a weak, infirm creature, but it is because you want the first principle of religion, a right belief in God. For as thankfulness is an express acknowledgement of the goodness of God towards you; so repinings and complaints are as plain accusations of God’s want of goodness towards you.
*On the other hand, would you know who is the greatest saint in the world? It is not he who _prays_ most, or _fasts_ most; it is not he who gives most _alms_, or is most eminent for temperance, chastity, or justice; but it is he who is _always thankful_ to God, who _wills_ every thing that God _willeth_, who receives every thing as an instance of God’s goodness, and has a heart always ready to praise God for it.
All prayer and devotion, fastings and repentance, meditation and retirement, all sacraments and ordinances, are but so many means to render the soul thus conformable to the will of God, and to fill it with thankfulness and praise for every thing that comes from God. This is the perfection of all virtues; and all virtues that do not tend to it, or proceed from it, are but so many false ornaments of a soul not converted unto God.
