Hebrews 4:12 (NRSV)
Indeed, the word of God is living and active, sharper than any two-edged sword, piercing until it divides soul from spirit, joints from marrow; it is able to judge the thoughts and intentions of the heart.
Ezekiel 3:1-3 (NRSV)
1 He said to me, O mortal, eat what is offered to you; eat this scroll, and go, speak to the house of Israel. 2 So I opened my mouth, and he gave me the scroll to eat. 3 He said to me, Mortal, eat this scroll that I give you and fill your stomach with it. Then I ate it; and in my mouth it was as sweet as honey.
2 Timothy 2:14-15 (NRSV)
14 Remind them of this, and warn them before God that they are to avoid wrangling over words, which does no good but only ruins those who are listening. 15 Do your best to present yourself to God as one approved by him, a worker who has no need to be ashamed, rightly explaining the word of truth.
