Exodus 36:2

And Moses called Bezaleel — "Even those whom God has qualified for, and inclined to the service of the tabernacle, yet must wait for a call to it, either extraordinary, as that of preachers and apostles, or ordinary, as that of pastors and teachers. And observe who they were that Moses called; those in whose heart God had put wisdom for this purpose, beyond their natural capacity, and whose heart stirred him up to come to the work in good earnest." Those are to be called to the building of the gospel tabernacle, whom God has by his grace made in some measure fit for the work, and free to it: ability and willingness, with resolution, are the two things to be regarded in the call of ministers.
