The foundation of true holiness and true Christian worship is the doctrine of the gospel, what we are to believe. So when Christian doctrine is neglected, forsaken, or corrupted, true holiness and worship will also be neglected, forsaken, and corrupted.

The most tremendous judgment of God in this world is the hardening of the hearts of men.

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.

It is evident that you contend against sin merely because of how it troubles you.

Indwelling sin always abides whilst we are in this world; therefore it is always to be mortified.

He that loves works out good to those that he loves, as he is able. God's power and will are equal; what He wills He works.

Let our hearts admit, “I am poor and weak. Satan is too subtle, too cunning, too powerful; he watches constantly for advantages over my soul. The world presses in upon me with all sorts of pressures, pleas, and pretences. My own corruption is violent, tumultuous, enticing, and entangling. As it conceives sin, it wars within me and against me. Occasions and opportunities for temptation are innumerable. No wonder I do not know how deeply involved I have been with sin. Therefore, on God alone will I rely for my keeping. I will continually look to Him.
