Lips
Lips symbolize communication. We must use discretion in using our lips for the good of others and for our own well-being. "He who guards his lips guards his life, but he who speaks rashly will come to ruin" (Proverbs 13:3). Despite all the harm we can cause with our words through gossip, lies and slander, if God is involved in our lives, our lips can honor the Lord and relay words of wisdom. More importantly the best thing we can do with our lips is to praise God and express our thankfulness to him. In turn, our praise to God can lead to telling others about his goodness. However, since "actions speak louder than word," we must consistently do what we say; otherwise, we will be seen as hypocrites, not witnesses.

Lips can be the source of foolishness, lies and other forms of wickedness, but they can also be a source of wisdom.
