Speak to the children of Israel, that they bring Me an offering. From everyone who gives it willingly with his heart you shall take My offering.
~ Exodus 25:2 (NKJV)
The Christian religion has always been a matter of the heart. Form and fashion means very little to the Lord if the follower of God does not approach Him “with his heart”. Yes, we are commanded to bring our offerings. Certainly we should seek diligently to worship and serve the Lord. But even higher and greater than these lofty tasks is the willingness of the child of God to perform them from a love for the Lord with his whole heart.
