From Kevin DeYoung’s Taking God At His Word:
The word of God is able to do many things–everything, really. God created by the word. Abraham was called by the word. The people were gathered as a nation at Sinai by the word. Their deliverance from Babylon was made firm by the word. Lazarus was raised by the word. The apostolic church was called into existence by the word. Throughout redemptive history we see God creating, cursing, calling, converting, gathering, blessing, equipping, threatening, and promising by his word. And in our personal history, we see the power of God’s word most clearly in its ability to save us (2 Tim. 3:15)
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, or 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. Don’t think you have nothing important to say in the world.Don’t worry whether you have anything helpful to share with hurting and needy people. Don’t despair that there is no transforming power in your life. Keep going in the gospel, and keep growing in the Scriptures. They are more than able.
