It is easy to point fingers. It is easier still to talk loud and long about what we think of others and their lives. It doesn't take any amount of character or brains to tear someone else down. The Bible really gives us a simple choice. We can either be critical or charitable. Being critical, setting ourselves up as a judge in someone else's life, is a sin.
Romans 14:13 Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way.
Charity, on the other hand, is love in action. It is moving away from a simple feeling of affection to displaying our love to others in acts of help and blessing.
1 Corinthians 16:14 Let all your things be done with charity.
If we could put all of your criticisms of others into a metal bucket and put all of your acts of charity into another bucket, and I had the ability to set just one of those buckets on fire; which one would you want burned up? Would you like to lose your criticisms, or your charity? What do you like better: being right or being kind?
God has told us to do all things with charity. He has not told us to do anything by way of criticism and knocking others down.
And so today, determine to operate out of charity instead of out of a critical spirit.
