In Exodus chapters 26-30, God gave Moses very detailed instructions about how to make the tabernacle, its furnishings, the priests’ garments, and all the instruments used in worship. And then in chapter 31, God tells Moses (much to Moses’ great relief, I imagine),

See, I have called by name Bezalel the son of Uri, son of Hur, of the tribe of Judah, and I have filled him with the Spirit of God, with ability and intelligence, with knowledge and all craftsmanship, to devise artistic designs, to work in gold, silver, and bronze, in cutting stones for setting, and in carving wood, to work in every craft. And behold, I have appointed with him Oholiab, the son of Ahisamach, of the tribe of Dan. And I have given to all able men ability, that they may make all that I have commanded you. (Exodus 31:2-6)

Then in Exodus 35 God commands anyone “of a generous heart” (v. 5) to contribute to the needs of constructing all these things. And the people were so stirred that they had to be “restrained” from continuing to give (Exodus 36:6).

Here’s the encouragement: when God calls us to do something, he provides all the necessary direction, ability, and resources to accomplish it.
