Until recently, I hadn't thought much about how important words -- both written and spoken -- are to God. Words are one of the most tangible ways He communicates with us (the Bible), and one of the most intimate ways we communicate with Him (through prayer). "Word" appears 962 times in the Bible (NIV version, at least).
The book of Proverbs likely has the most to say about our words and how we use them. For example:
Wise words are like deep waters. Prov. 18:4 (NLT)
Wise words are more valuable than much gold and many rubies. Prov. 20:15 (NLT)
In the book of John, God describes Jesus as "the Word."
In the beginning was the Word, and the Word was with God, and the Word was God.
But I think my favorite passage about the power of words is in 2 Corinthians 3:3 (NIV):
You are a letter from Christ ... written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.
I pray that the letter I am displaying to others is one of compassion, hope, and faith in a God whose love for His children is not limited to words, but speaks volumes.
