3. And by faith, taken in its more particular meaning, for a confidence in a pardoning God, we establish his law in our own hearts, in a still more effectual manner. For there is no motive which so powerfully inclines us to love God, as the sense of the love of God in Christ. Nothing enables us like a piercing conviction of this, to give our hearts to him who was given for us. And from this principle of grateful love to God, arises love to our brother also. Neither can we avoid loving our neighbour, if we truly believe the love wherewith God hath loved us. Now this love to man grounded on faith and love to God, _worketh no ill to_ our _neighbour_. Consequently, it is (as the Apostle observes) _the fulfilling of the_ whole negative _law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet: and if there be any other commandment, it is briefly comprehended in this saying, Thou shalt love thy neighbour as thyself._ Neither is love content with barely working no evil to our neighbour. It continually incites us to do good: as we have time, and opportunity, to do good in every possible kind and in every possible degree to all men. It is therefore the fulfilling of the positive likewise, as well as of the negative law of God.
4. Nor does faith fulfil either the negative or positive law, as to the external part only: but it works inwardly by love, to the purifying of the heart, the cleansing it from all vile affections. _Every one that hath this_ faith _in him purifieth himself even as he is pure_: purifieth himself from every earthly, sensual desire, from all vile and inordinate affections: yea, from the whole of that carnal mind, which is enmity against God. At the same time, if it have its perfect work, it fills him with all goodness, righteousness and truth. It brings all heaven into his soul, and causes him to walk in the light even as God is in the light.
5. Let us thus endeavour to establish the law in ourselves: not sinning, _because we are under grace_, but rather using all the power we receive thereby, _to fulfil all righteousness_. Calling to mind, what light we received from God, while his Spirit was convincing us of sin, let us beware we do not put out that light; what we had then attained let us hold fast. Let nothing induce us to build again what we have destroyed; to resume any thing, small or great, which we then clearly saw was not for the glory of God, or the profit of our own soul: or to neglect any thing, small or great, which we could not then neglect, without a check from our own conscience. To increase and perfect the light which we had before, let us now add the light of faith. Confirm we the former gift of God, by a deeper sense of whatever he had then shewn us; by a greater tenderness of conscience, and a more exquisite sensibility of sin. Walking now with joy and not with fear, in a clear, steady sight of things eternal, we shall look on pleasure, wealth, praise, all the things of earth, as on bubbles upon the water: counting nothing important, nothing desirable, nothing worth a deliberate thought, but only what is _within the veil_, where _Jesus sitteth at the right hand of God_.
6. Can _you_ say, _Thou art merciful to_ my _unrighteousness: my sins thou rememberest no more_? *Then for the time to come, see that you fly from sin, as from the face of a serpent. For how exceeding sinful does it appear to you now? How heinous above all expression? On the other hand, in how amiable a light do you now see the holy and perfect will of God? Now therefore labour that it may be fulfilled, both in you, by you, and upon you. Now watch and pray that you may sin no more, that you may see and shun the least transgression of his law. You see the motes which you could not see before, when the sun shines into a dark place. In like manner, you see the sins which you could not see before, now the Sun of Righteousness shines in your heart. Now then do all diligence to walk in every respect, according to the light you have received. Now be zealous to receive more light daily, more of the knowledge and love of God, more of the Spirit of Christ, more of his life, and of the power of his resurrection. Now use all the knowledge, and love, and life, and power you have already attained. So shall you continually go on from faith to faith. So shall you daily increase in holy love, till faith is swallowed up in sight, and the law of love established to all eternity.
