In the service of the Lord, God gives us everything we need. He does this as a creator, as well as a conductor. Often the two overlap. When he does this, he does it with exceeding grace and overflowing blessings. As they were building the tabernacle, the Hebrew people freely gave what they had. These riches were first given to them, as they had been slaves previously. The amount that they gave overflowed the necessary specifications. This is a good indication that God had no desire to bleed man dry in his worship. Much the same that Abraham was to bring a sacrifice, that sacrifice was given to him to give. Beyond this, he had given them enough skilled craftsmen that they would be able to accomplish the task, even with rudimentary tools in the dessert. God was not unreasonable about his plans. In fact, these artists probably felt a deep sense of invigoration as they spearheaded a project that their unique gifting had been primed for. It is a good argument for the idea that a Spiritual Gifts can exist in the enabling of artistry and craftsmanship. In everything, we see that the art of worshipping God is a communal process. God calls for it, and he enables it. Men respond to it and they give what they have been given to accomplish it.
