Jesus’ message about giving is both clear and simple: (1) Give, (2) Give purely, and (3) Give purely to glorify God and motivate others. Rather than concerning yourself with who will know about your giving, focus on who will be glorified by your giving and inspired to join you in giving adventures.
For those of us who wish to be useful stewards to the Owner, there are two essential attitudes that must be part of our spiritual and emotional makeup. The first is humility. True humility can only be acquired in death of self, transforming us from being internally focused to being externally focused.
