Scripture doesn’t tell us everything we may want to know about everything. But it tells us everything we need to know about the most important things. It gives us something the Internet, with all its terabytes of information never could: wisdom. The purpose of Holy Scripture is not ultimately to make you smart, or make you relevant, or make you rich, get you a job, or get you married, or take all your problems away, or tell you where to live. The aim is that you might be wise enough to put your faith in Christ and be saved.
Nothing else in all the world has this ability. The word of the president is important. The word of your parents is to be honored. The word of your spouse is to be treasured. But only the word of God can save. Only in Scripture do we encounter the fullness of God’s self-disclosure. Only in Scripture do we find the good news of the forgiveness of sins. Only in Scripture can we be led to believe in Jesus Christ and, by believing, have life in his name.
