We should never think that once we have given some money and time to the Lord that the rest is ours to do with as we please. All that we have belongs to God, so He should be taken into consideration in everything we do.
The fear of the Lord helps us recognize our accountability to God for the stewardship of leadership. It motivates us to seek the Lord's wisdom and understanding in difficult situations. And it challenges us to give our all to the Lord by serving those we lead with love and humility.
If your investments are limited to this earth, you are the world's worst investor.
