Offerings, sometimes called sacrifices are a common way people express their gratitude in response to protection from a god or gods.
Offerings can come in a variety of forms, from treasures such as gold and silver, to the fruits of harvest or wild game hunted in the mountains or caught from the sea. Sometimes offerings are monetary donations that come from a person’s salary.
Although the gods do not actually eat these food offerings or use the money; they are offered with the belief that they will accept the sincere heart of the person making the offerings.
But in the divine directions, offerings of physical materials are not solicited from God. It is the offering of the pure mind that God accepts.
Sah, offer to Me your minds filled with promise, filled with promise. Then I shall accept, I shall accept. If you do it with tears, with tears, God cannot accept. Do not bring Me things worth a million. It is the sincere mind of a single cent that I accept. Osashizu, July 20, 1902
In summary, when church solicitations come along, contribute as much as you feel comfortable; Offer to God, to purify your mind of greed, arrogance, and self love. Do it with sincerity and without any emotional attachments, and God will accept your resolution and provide any protection.
