Do you love enough to lay down your life?Do you love enough to give 100%?
See? I can do that too.
There is a universal non-optional principle at work. Christ cited it saying, "Where your treasure is, your heart will be also."
The tithe is a trapping of the law. It doesn't matter that one gives 10% if he does so begrudingly. It is cheerful, willing giving in which God is interested. And if one's heart is in the Gospel, it will be evident by the way he manages and allocates his resources.
