The Bible being sufficient for life means that Christians must rely on the Scriptures to deal with life’s problems. Holding to the sufficiency of Scriptures makes the Bible the go to place for wisdom, guidance, and direction. Looking at the biblical texts that support the sufficiency of Scripture can help us understand what this reality means for us. Paul in 2 Timothy 3:17, states that the Scriptures make one “competent, equipped for every good work”. Not only is the Bible sufficient to point an unbeliever to salvation in Christ, the Bible also makes that new believer, complete, able to deal with the problems of life to the glory of God.
The next important text comes in 2 Peter 1:3 that states that “His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us”. When it comes to helping someone deal with the problems of life and pursue godliness, we must not think we need some new thing as if we did not have what we need. God has granted to us what we need in the Scriptures; it is up to us to use it. Another text that is helpful in understanding the sufficiency of the Bible is found in Hebrews 4:12. There we see that the word of God is able to expose the problems of the heart and bring about repentance. The text is used to highlight the power that comes through the words of the Scriptures. The Bible is able to expose the problems we are having so that they can be solved. No other book or person can claim what the Bible does about itself. There are many other places in Scripture to point to its sufficiency such as Psalm 19 and 119 but these three texts highlight what it means for the Bible to be sufficient for life.
