Human beings tend to make financial matters more difficult than they should be, so tithing can seem very complicated. When it comes to giving money back to God, He doesn’t care about the amount; instead He cares about your heart and your intentions. A faithful, cheerful giver who gives little is more pleasing than a begrudging giver who gives more.
Jesus called his disciples to him and said, “I tell you the truth, this poor widow has given more than all the others who are making contributions. For they gave a tiny part of their surplus, but she, poor as she is, has given everything she had to live on.
~ Mark 12:43-44 [NLT]
