You must be born again

Outward reformation only (though of excellent use) is but a new appearance, not a new creature, a change of life, not of the heart; whereas this work we discourse of is a new birth in the understanding and will; it begins at the spirit and descends from thence to the body; it is a sanctification in spirit, soul, and then body.

Stephen Charnock

Honoring with their Lips

Men profess they know the truth; but they know it not in its proper order, in its harmony and use.  It leads them not to Christ, it brings not Christ unto them; and so is lifeless and useless.  Hence, ofttimes, none are more estranged from the life of God than such as have much notional knowledge of the doctrines of the Scripture.

John Owen

Righteous Judgment

And then let us never look upon any sin as light and inconsiderable; but be fully persuaded, that the smallest is infinitely heinous in the sight of God, and prejudicial to the souls of men; and that, if we had the right sense of things, we should be as deeply affected with the least irregularities, as now we are with the highest crimes.

Henry Scougal

He is the Potter

A piece of lead, while it is in the lump, can be put to no use, but melt it, and you may then cast it into any mould, and it is made useful.  So a heart that is hardened into a lump of sin is good for nothing, but when it is dissolved by repentance, it is useful.  A melting heart is fit to pray.

Thomas Watson

O Wretched Man That I Am

Why does faith act no stronger but because it is clogged with sense?  Why does love to God burn no purer but because it is hindered with lust?  Original sin incorporates with our graces.  As bad lungs cause an asthma or shortness of breath, so original sin having infected our heart, our graces now breathe very faintly.
