There is a test of faith for everyone who is a believer in Christ. Early on in the Christian life, and at intervals afterwards, some great test of faith will come. We are not likely to stand if we are not resolved in our hearts to obey the Lord no matter what, and to serve him no matter what. If I should be a limp sort of Christian, then when the test comes I'll fall all the more easily and quickly, and this was a massive test.
God gave them knowledge beyond their own. We have seen it in the church. People are converted; they are naturally quite simple, not endowed with intellect, and yet God gives understanding beyond their natural gift, the ability to see through things and to see deep things, new aptitudes.
