It is not in the fact that God ever sets His approval upon ignorance. That is not the thought, but God must have spiritual men to do the work of the kingdom. We have seen God use the ripest scholarship with the greatest natural gifts, and some men with the greatest brain power have been the most spiritual men of the ages, but there are not many of that class.
We will take the case of Paul and Peter. They were both deeply spiritual, they were both splendid commanders, but Paul had the advantage of Peter intellectually, therefore he was used of the Lord to write more books than any other man had ever written of sacred history. But it matters not how intellectual a man is, if the Spirit of the Lord is not in him, the Lord can not use him for spiritual work.
Barnabas was evidently a God-called and a Spirit-filled man, for no man can read of Barnabas without seeing that God's seal was upon him and upon his ministry, for in Acts 11th chapter 24th verse, Luke said emphatically, "He was a good man and full of faith, and of the Holy Ghost, and much people was added to the Lord." The most beautiful thought to my mind is brought out in this most remarkable statement by the divine writer, that Barnabas was a good man.
Goodness is a most precious possession, and it has been discovered that goodness will carry an apology for almost every defect that we may have, but we are told by Bible translators that the word good means more than merely morally good. It means that Barnabas was kind, affectionate, and attractive. Indeed, the commentators tell us that the word may be construed with equal propriety that Barnabas was a beautiful man. He was good or he was beautiful, just as you like it; in fact, in the kingdom of God goodness and beauty are one and the same thing.
