Snow

 Like the cold of snow in the time of harvest is a faithful messenger to those who send him; he refreshes the soul of his masters. Like clouds and wind without rain is a man who boasts of a gift he does not give.
Proverbs 25:13-14 ESV

These two proverbs contrast two men. The first is like the cold of snow in the time of harvest, he refreshes the soul of his masters. This is someone we want to emulate. We become like that man by being a faithful messenger.

No one likes a bearer of bad news. But it's better to share the truth than to flatter with lies. The second man is not to emulate. He's like clouds and wind without rain.

In the UK, where it often rains, that doesn't sound so bad. But in a dry and arid land, clouds and wind without rain promise much but deliver nothing. There's no point boasting of how generous we are if we're not. We deceive ourselves and our hearers, and give false hope if we do. That's not how we should be.

"Dear Yahweh our God, may we be faithful messengers. Forbid that we should be boastful of things we have no right to boast of, but let us boast in Christ, in His name, amen"
