Exodus 25:2 - Tell the sons of Israel to raise a contribution for Me; from every man whose heart moves him you shall raise my contribution.
You see, our giving, our tithe, is directly tied to our hearts. The word for moves in this passage means "to incite, impel, make willing" (Strong's). So God wanted an offering from those whose heart's made them willing. An offering, or contribution, to our God shouldn't be something we do begrudgingly - "We should ask, not only 'What must we do?' but, 'What may we do?' Whatever they gave, they must give it cheerfully." Giving must come from a willing and cheerful heart - we shouldn't view our giving and tithe as something we have to do, but rather, something that we get to do!
The next time you go to give an offering or tithe I challenge you to examine your heart:
Are you willing and joyful?
Or are you sitting there thinking of everything else you could be doing with that money and reluctantly placing it in the offering plate?
I have been guilty of the latter a few times but I am striving every day to remain joyful and willing to give God all that my heart moves me too!
