6. It is opposed to sinking discouragements. God would have us to depend on Him though we do not see how the thing may be brought about; otherwise, we do not show a quiet spirit.
7. It is opposed to sinful shiftings and shirkings to get relief and help. Thus do many, through the corruption of their hearts and the weakness of their faith, because they are not able to trust God and follow Him fully in all things and always. For this reason, the Lord often follows the saints with many sore temporal crosses as we see in the case of Jacob, though they obtain the mercy. It may be that your carnal heart thinks, “I do not care how I am delivered, if only I may be freed from it.” Your hearts are far from being quiet!
8. The last thing that quietness of spirit is the opposite of is desperate risings of the heart against God by way of rebellion. That is the most abominable. They find in their hearts something of a rising against God. Their thoughts begin to bubble, and their affections begin to move in rebellion against God Himself. This is especially the case with those, who besides their corruptions, have a large measure of melancholy. The devil works both upon the corruptions of their hearts and the melancholy disease of their bodies. Now Christian quietness is opposed to all these things. When affliction comes, whatever it is, you do not murmur or repine, you do not fret or vex yourself.
