Here is a good devotional I got from Ed Young's Ministry today.
Set a guard over my mouth, O Lord; keep watch over the door of my lips. Let not my heart be drawn to what is evil, to take part in wicked deeds with men who are evildoers; let me not eat of their delicacies.
Saying we have faith in Jesus is one thing. But putting substance behind those words is another thing entirely. If you call yourself a Christ follower, God calls you to display an authentic faith. And you do that by guarding the words that come from your mouth, not just the thoughts you have in your mind.
In this passage, David asks God to put a guard over his mouth because he knew that the words he spoke did more than just communicate what was on his mind. The words we choose communicate the truth about our faith in God.
If your heart has been transformed by Christ, it's time to take an honest look at the words you speak to those around you. Do those words reflect your transformed heart? Ask God to help you choose only those words that will honor him and reflect the truth about your faith in him.
A Prayer for Today
Dear Lord, I know that the words I choose do more than just reflect a thought or feeling; I know that they reflect my faith in you. Because of that, help me to choose words that will point others to you. In Jesus' name I pray, Amen.
