Jesus said, "Be careful not to do your ‘acts of righteousness’ before men, to be seen of them. If you do you, you will have no reward from your Father in heaven" (Matthew 6:1, NIV). Katie Kellogg wrote:
Not Even a Whisper?
I do my good deeds secretly.
No words must get about.
Still, it is rather annoying
When not a word leaks out.
