Tithing is a concrete and consistent way to show that you believe in the mission, and you want to help the church/community reach the ends of the earth. It’s an investment that God multiplies a hundred fold for the conversion of hearts. Yes, your generous tithe goes a very long way, even if it’s small, because God can take a humble offering from a heart full of love, and make it something truly beautiful for His kingdom.
And he sat down opposite the treasury, and watched the multitude putting money into the treasury. Many rich people put in large sums. And a poor widow came, and put in two copper coins, which make a penny. And he called his disciples to him, and said to them, “Truly, I say to you, this poor widow has put in more than all those who are contributing to the treasury. For they all contributed out of their abundance; but she out of her poverty has put in everything she had, her whole living.”
–Mark 12:41–44
