IV. The second part of Christian liberty, which is dependent on the first, is, that their consciences do not observe the law, as being under any legal obligation; but that, being liberated from the yoke of the law, they yield a voluntary obedience to the will of God. For being possessed with perpetual terrors, as long as they remain under the dominion of the law, they will never engage with alacrity and promptitude in the service of God, unless they have previously received this liberty. We shall more easily and clearly discover the design of these things from an example. The precept of the law is, “Thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.”[228] That this command may be fulfilled, our soul must be previously divested of every other perception and thought, our heart must be freed from all desires, and our might must be collected and contracted to this one point. Those who, compared with others, have made a very considerable progress in the way of the Lord, are yet at an immense distance from this perfection. For though they love God with their soul, and with sincere affection of heart, yet they have still much of their heart and soul occupied by carnal desires, which retard their progress towards God. They do indeed press forward with strong exertions, but the flesh partly debilitates their strength, and partly attracts it to itself. What can they do in this case, when they perceive that they are so far from observing the law? They wish, they aspire, they endeavour, but they do nothing with the perfection that is required. If they advert to the law, they see that every work they attempt or meditate is accursed. Nor is there the least reason for any person to deceive himself, by concluding that an action is not necessarily altogether evil, because it is imperfect, and that therefore the good part of it is accepted by God. For the law, requiring perfect love, condemns all imperfection, unless its rigour be mitigated. Let him consider his work, therefore, which he wished to be thought partly good, and he will find that very work to be a transgression of the law, because it is imperfect.
