Meditate on this power of God, and press it often upon your minds. We conclude many things of God that we do not practically suck the comfort of, for want of deep thoughts of it, and frequent inspection into it. We believe God to be true, yet distrust him; we acknowledge him powerful, yet fear the motion of every straw. Many truths, though assented to in our understandings, are kept under hatches by corrupt affections, and have not their due influence , becausae they are not brought forth into the open air of our souls by meditation. (Volume II, p. 102)
Many of my readers believe in the great power of God, but few of us could write for over a hundred pages on it, "for want of deep thoughts of it." This is what I love Charnock for; he enables me to meditate on who God is in greater depth than I am capable of on my own. That's why he's my Sunday reading.
