Great winds and storms help fruit-bearing trees. So also do corruptions and temptations help the fruitfulness of grace and holiness. The storm loosens the earth round its roots so the tree is able to get its roots deeper into the earth, where it receives fresh supplies of nourishment. But only much later will it be seen to bring forth better fruit. So corruptions and temptations develop the roots of humility, self-abasement and mourning in a deeper search for that grace by which holiness grows strong. But only later will there be visible fruits of increased holiness.

It is not the distance of the earth from the sun, nor the sun's withdrawing itself, that makes a dark and gloomy day; but the interposition of clouds and vaporous exhalations. Neither is thy soul beyond the reach of the promise, nor does God withdraw Himself; but the vapours of thy carnal, unbelieving heart do cloud thee.

The indulgence of one sin opens the door to further sins. The indulgence of one sin diverts the soul from the use of those means by which all other sins should be resisted.

If our principal treasure be as we profess, in things spiritual and heavenly, and woe unto us if it be not so! on them will our affections, and consequently our desires and thoughts, be principally fixed.

On Christ’s glory I would fix all my thoughts and desires, and the more I see of the glory of Christ, the more the painted beauties of this world will wither in my eyes and I will be more and more crucified to this world. It will become to me like something dead and putrid, impossible for me to enjoy.

Sin also carries on its war by entangling the affections and drawing them into an alliance against the mind. Grace may be enthroned in the mind, but if sin controls the affections, it has seized a fort from which it will continually assault the soul. Hence, as we shall see, mortification is chiefly directed to take place upon the affections.

The person who understands the evil in his own heart is the only person who is useful, fruitful, and solid in his beliefs and obedience. Others only delude themselves and thus upset families, churches, and all other relationships. In their self-pride and judgment of others, they show great inconsistency.
