Jeremiah Burroughs said this quote

A godly man in the midst of the waves and storms that he meets with can see the glory of heaven before him and so contents himself. One drop of the sweetness of heaven is enough to take away all the sourness and bitterness of all the afflictions in the world. We know that one drop of sourness, or one drop of gall will make bitter a great deal of it; but if you put a spoonful of gall into a cup of sugar, it will embitter that. Now it is otherwise in heaven: one drop of sweetness will sweeten a great deal of sour affliction, but a great deal of sourness and gall will not embitter a soul who sees the glory of heaven that is to come.

Christian contentment is that sweet, inward, quiet, gracious frame of spirit, which freely submits to and delights in God's wise and fatherly disposal in every condition.

~ Jeremiah Burroughs

Thou hast gone on in all thy life hitherto, ever since thou wast born, in a continual opposition to God Himself, unto the infinite Lord, the eternal first being of all the world; thy life hath been nothing but enmity to this God: thou hast as directly opposed, and striven against, and resisted Him, as ever man did oppose, and resist, and strive with another man, and this thou hast done in the whole course of thy life: certainly there is more in this to humble a man than anything that can be spoken to shew him the evil of sin.

~ Jeremiah Burroughs

As in a tree, there is more sap in an Arm of the tree, than in a little sprig; but the sprig hath the same sap for kind that the Arm of the tree hath, and it all comes from the same root. So though there be more venom in some gross, crying sins, than in some others; yet there is no sin but hath the same sap, and the same venom, for the kind, that every sin hath, that the worst sin hath.
