You study your Bible and learn what it says and what it means. Your study includes personal Bible study, listening to preachers, and discussing theological truths with Christian friends. You desire to know God. You want to know Him, but not on a superficial shallow way, but to know the deep truths in the Bible.
As you yearn to know those deep truths, you feel a sense of inadequacy. In fact, the more your study, the more you find Bible truths you just plain don’t understand. This causes you to question why you do not understand the Bible fully. Thus, this causes you to feel inadequate. A theological student came to Charles Spurgeon one day, greatly concerned that he could not grasp the meaning of certain verses in the Bible. The noted preacher replied kindly but firmly, “Young man, allow me give you this word of advice. Give the Lord credit for knowing things you don’t understand.” Now, that is some good advice worth taking. God knows way more than is revealed in Scripture. And if Christ is omniscient, then you should expect Him to know more than you do.
David is known as a man after God’s own heart. His whole desire in life was to be well pleasing to the Lord. As David lifts his soul to God for protection, guidance, and pardon, he pens these words: “Make me know Your ways, O Lord, teach me your paths” (Psalm 25:4). The reason David makes this request is that he realizes that He does not fully know the Lord God. So, he asks God to teach him the ways he is to live his life.
Yes, in your Bible study put forth the effect to learn all you can about the Lord and how to live on earth. But knowing all the unsearchable things should be left to God.
