I questioned giving to God my leftovers after a garage sales several years ago. People told me God wants everything I can give HIm. He just appreciates my giving.
I just could not agree with that. I believed God should receive our "first fruits," meaning our best.
Leftovers. Think, leftover time, leftover money, leftover talents, after we satisfy ourselves.
More to consider. Your boss gives you his leftovers after his own salary, your children given you time and affection after their own fun and friends. That makes it pretty sad doesn't it?
Look to the Bible for an answer. David's view, his giving depended on"that which cost me nothing." Right view! Also shows love in your giving.
Then remember Paul in Romans 12:1, "Present your bodies a living sacrifice...." nothing costs more than that. The best is to be given and that means everything, to God.
I do believe He doesn't accept seconds after we are through with them.
I have been giving our church books from my own bookshelves. I cannot say I am giving them to God, but after I make sure they are okay I can give them to members of our church and hope they like them as I have.
Hope you agree.
