For better or for worse (but not about marriage)
Individual believers and churches demonstrate their love or lack of love by the way that they treat (for better or for worse) people who are different from them.
Individual believers and churches demonstrate their sevant’s heart or lack thereof by the way that they serve (for better or for worse) others when they are at their neediest.
Individual believers and churches demonstrate their fellowship or lack of fellowship by the way they share with one another (for better or for worse) when people are hurting and their lives are messy.
Individual believers and churches demonstrate their hospitality or lack of hospitality by how they share their possessions and time (for better or for worse) when they have very little to share.
Individual believers and churches demonstrate their unity or lack of unity by how they accept others (for better or for worse) when they are not accepted themselves.
That last one is tough. Could that also be translated as: Individual believers and churches demonstrate what is in the heart when they get their feelings hurt? Do they isolate and become bitter, or do they make a decision to love. Love your (church) enemies. Reminds me of what Steve Brown (Key life) said or quoted: Never be a servant until you don’t have to be. Now you think about that.
