Our words matter. The first reading from the Old Testament Book of Sirach also brings home that point. "Praise no one before he speaks, for it is then that people are tested."
How much sin do we commit with the use of our speech? Do we lie? Do we slander? Do we curse? Do we gossip? I would invite you to read the Scripture readings for this Sunday and prayerfully meditate upon the messages contained therein all throughout the week. Then let God's grace flow through you this Sunday when those same readings are proclaimed.
"Think twice before you speak, because your words and influence will plant the seed of either success or failure in the mind of another."
