John Wesley on Hebrews 4:12

For the word of God - Preached, Heb 4:2, and armed with threatenings, Heb 4:3. Is living and powerful - Attended with the power of the living God, and conveying either life or death to the hearers. Sharper than any two - edged sword - Penetrating the heart more than this does the body. Piercing - Quite through, and laying open. The soul and spirit, joints and marrow - The inmost recesses of the mind, which the apostle beautifully and strongly expresses by this heap of figurative words. And is a discerner - Not only of the thoughts, but also of the intentions.
