Perhaps it would be helpful to understand that the basic meaning of the Hebrew word translated as “wisdom” is equivalent to the English word “skill.” Solomon, in Proverbs 4:7, tells us, “Wisdom is the principal thing; therefore get wisdom.” He is really saying, “Above all things, get skill.” Skill in what? Skill in living. God wants us to be skilled in living. In this case, God has filled Bezaleel with wisdom, and this wisdom has to do with the responsibility that He had given to him in constructing the Tabernacle and it furnishings and utensils.
This principle becomes vital to us in regard to our place in the church of God, understanding about the Spirit of God, and understanding about God Himself and what He does in our conversion. These verses show that God Himself was personally and directly involved by means of His Spirit enhancing the natural and developed abilities of humans involved in His work. Bezaleel and Aholiab already had skill, but what God did to enable them to perform a function directly for Him is that He increased their natural ability to enable them to function at a higher level than normal. A supernatural element was added to their lives.
If God did this for Bazaleel and Aholiab, will He not also do it for us? Will He not give us powers greater than we have by nature? He does this by His Spirit and by stirring up the spirit in man.
If we follow the usage for “spirit” and apply it here, we see that “spirit” is an invisible and immaterial source of some sort of needed power, but in this case, it is external to mankind—supernatural. In other words, we can communicate spirit from one person to another, but that spirit will only be what any human is capable of. As we become more skilled, our ability to project or to communicate spirit to another person is also increased as well, but we reach a limit in our human ability to do this. However, God is showing that in order to do a work for Him, He will empower us to go beyond what is normally possible for a human being to do.
God gave these craftsmen supernatural power for them to operate in His behalf, to produce good fruit within His purpose of God, and therefore it was of God. However, when we see abilities that seem to be beyond the ken of a normal human being, we may not know the identity of the supernatural force or power until we begin to see its fruit: “You will know them by their fruits” (Matthew 7:16).
