If I have observed anything by experience, it is this: a man may take the measure of his growth and decay in grace according to his thoughts and meditations upon the person of Christ, and the glory of Christ's Kingdom, and of His love.

The duties God requires of us are not in proportion to the strength we possess in ourselves. Rather, they are proportional to the resources available to us in Christ. We do not have the ability in ourselves to accomplish the least of God's tasks. This is the law of grace. When we recognize it is impossible for us to perform a duty in our own strength, we will discover the secret of its accomplishment.

Sin will be always acting, if we be not always mortifying, we are lost creatures.

We are never nearer Christ than when we find ourselves lost in a holy amazement at His unspeakable love.

When sin lets us alone we may let sin alone.

A man preacheth that sermon only well unto others which preacheth itself in his own soul. And he that doth not feed on and thrive in the digestion of the food which he provides for others will scarce make it savoury unto them; yea, he knows not but the food he hath provided may be poison, unless he have really tasted of it himself. If the word do not dwell with power in us, it will not pass with power from us.

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