Christ inviting sinners to come to him for rest

First, Because the life of Grace, wheresoever it is, is a very tender and delicate thing; nothing is so delicate and tender as the life of Grace, and therefore it must needs be sensible of this burden of Corruption according to what degree it doth remain in the Soul. As thus, you know a man or Woman, the more delicate and tender they are in their flesh, having had very curious bringing up, or it may be their natural Spirits are very delicate more then other men, some men their natural spirits are more gross, and can bear burdens with less sense, but now those that are more finer and delicate, ⟨p. 76⟩if you lay a burden upon them, Oh! How burdensome is it unto them, now Grace makes the constitution to be delicate, fine, and pure; a pure constitution, it puts the Hearts into a most pure constitution, and therefore it must needs be sensible of the evil of sin according to the remainers of it.

Secondly, Where Grace is, Corruption must needs be very burdensome in this regard also, because that Grace keeps the Soul in continual action and stirring, now look as a man that hath a Leg that is broken, if he could lie still, and never stir, it would not be so grievous and burdensome to him, the pain and breaking of his Leg would not be so burdensome if he could lie still, but if this man, whose Leg is broken, must be stirring, walking, and going up and down, Oh! how burdensome is it that his Leg is broke. So it is with the Soul, it is true, if the Soul might be still a sleep, and doing nothing, then, though there be Corruption in them, it would not be so grievous, I but Grace wherever it is puts the Soul unto action; and therefore it is called, the divine Nature, because it is active, it puts the Soul on to be acting for God, and in the ways of life, now Grace putting the Soul to be acting, and Corruption that being as the breaking of the bones, it must needs be very burdensome, that which most hinders their activity of Grace must needs be very burdensome. You had need therefore take heed what you do when temptation to sin comes, take heed you do not break your bones, and your Legs, Why? Because when you have broken them you must be still stirring and acting for God. A poor man, it is a great deal worse for him, if he break his Leg, then a Rich man; a Rich man may sit by the fire, or lie in his bed a month together, but a poor man, if he break his Leg he doth not know what to do, he must to work, perhaps he cannot have that harbour that a Rich man may have, so I say, those that are of sluggish spirits, though Corruption prevail it is
