We learn first in this passage, that honest obedience to God’s will is one way to obtain clear spiritual knowledge. Our Lord says, “If any man will do His will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.”

The difficulty of finding out “what is truth” in religion is a common subject of complaint among men. They point to the many differences which prevail among Christians on matters of doctrine, and profess to be unable to decide who is right. In thousands of cases this professed inability to find out truth becomes an excuse for living without any religion at all.
