Hebrews 4:11-13 (ESV)
“11Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. 12For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. 13And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account.”
In N.T. Wright’s commentary Hebrews for Everyone, he makes the following statement:
“To spend time, prayerfully and thoughtfully, with scripture and and with Jesus, the written and living Word of God, is to know that gentle but powerful touch, like a very sharp and fine blade, producing surprising and perhaps alarming results. …With God’s word there are no accidents. God’s word is alive, as verse 12 declares; and the purpose of the two-edged sword is always to cleanse and heal.” (p.42)
