Salvation has never depended on possessing or fully understanding the written Bible but on trusting in Jesus Christ, the living Word, and His finished work on the cross (John 1:1–14). Throughout history, people came to faith by hearing the message of the gospel, as “faith comes from hearing… the word of Christ” (Romans 10:17), long before the Bible was compiled or widely available. But it is in Scripture that we learn that salvation comes through hearing and believing the truth about Christ (Ephesians 1:13).
At the same time, God's Word is perfect and contains the life-giving truth that revives the soul and guards us from sin (Psalm 19:7–11; Psalm 119:11). Jesus Himself affirmed that God’s Word is truth and essential for spiritual growth (John 17:17). This creates a clear tension: ignorance of God's Word does not prevent salvation, but rejecting it is ultimately rejecting the truth God has revealed. The solution is to trust in Jesus for salvation and then fully embrace God’s Word as truth, allowing it to shape, deepen, and anchor our faith.
Today, in the free world, we have access to God's written Word; we have the ability to read and study the Scriptures. But in other places around the world where there are dictators and ungodly leaders or where God's Word has not yet been translated, people do not even know there is a Bible or have access to it. So, when an unsaved individual hears the message of salvation through the death, burial and resurrection of Christ for their sins that person doesn't even know what the Bible says; they cannot possibly believe or not believe it. What they will believe is the message they have heard from the people who bring them the good news. Are these people not saved because they do not believe the Bible is God's Word? No!
The good news is that Jesus is the Living Word given to us by the Father; when a person places faith in Jesus he or she becomes a child of God. The faith may be a childlike faith, without knowledge, however, if they clearly understand their sinful condition and repent and believe the Gospel, Jesus will save them. Still, the Bible is God's Word and in it we understand who God is, how He has worked in human history, who we are, and how He calls us to live. The Holy Spirit uses God's Word to convict us of sin and grow us into mature believers. So, if anyone has God's Word and rejects its authority, they are rejecting God Himself. But if they do not have God's Word or do not yet understand it, they can still be saved.
