Stewardship, in part, means not being guilty of treating the Lord's offerings with contempt.
I'm reading through the Bible again this year in the New Living Translation. In 1 Samuel, Hophni and Phineas, the sons of Eli, are judged by God via death because they "treated the LORD's offering with contempt." For those of us in professional ministry, that's often a temptation. We forget that just because it's in our budget doesn't mean that it's our money. God forbid.
But it's also true of all of us in another sense. It's true when we treat the things the Lord gives us with contempt. Possessions we trash instead of pass along. Relationships we use instead of value. Jobs in which we surf instead of produce. That's contempt too for what the Lord has given us.
But that's just me thinking thoughts.
