 
How sweet are your words to my taste, sweeter than honey to my mouth!
Psalm 119:103 ESV
The Bible is the Word of God by its immeasurable majesty, moral purity, essential unity, and time-tested faithfulness. The Bible is unique in its power to convince and convert our hearts, comfort and build-up our spirits, and divide and measure our motives. The Bible is encouragement in trial, insight into the tribulations of life, and guidance in the midst of confusion. The Bible is the only book whose author can personally and directly apply its truths to our daily lives.
The Word of God is in your heart. The Word digs in this soil so that the spring may gush out.
Origen quoted in Ancient Christian Devotional: A Year of Weekly Readings, Lectionary Cycle B, ed., Thomas C. Oden and Cindy Crosby [Kindle Edition] (Downers Grove, IL: InterVarsity, 2011).
