Before we are made alive to God, we’re controlled mostly by what we want. But after we become alive to Him, we have a new desire to be governed by His will. In other words, the true Christian has a new compulsion to do what God wants him to do. And that information is found in the Bible.
A classic text on the sufficiency of Scripture for the Christian is 2 Tim. 3:16-17 : “All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work.”
Words like teaching, rebuking, correcting, and training are all growth-related words. When you are growing as a child of God, you can regularly point to how the Word of God has been teaching you, how it has reproved you for sin, how it has shown you how to correct mistakes in your life. And you can point to how the Bible has been training you to live in new ways God says are right.
I hear people who are moving forward in the things of God telling me how they are having new insights into the truth of Scripture, how God has used the Bible to give them direction for a career or ministry, how the Lord has reproved them about materialism or family failures or prayerlessness, and how He has corrected them.
Can you point to specific ways the Word of God has been doing this in your life during the past months? If so, you are growing in grace.
