Gossip or Concern

When is it gossip and when is it legitimately sharing a concern?

Wayne Mack provides a helpful outline in his book, Your Family, God's Way, that I will tweak into question form:

1. Have biblical attempts been made; but failed to resolve the difficulties?
2. Is your motivation for sharing a sincere desire to get help?
3. Are you sharing with those that actually can (and will) furnish godly counseling and solutions?
4. Will the information be helpful to others in a preventative, protective, or restorative way?
