Why is believing the Word of God important for Christians?

For Christians, believing in the entirety of God's Word is crucial as it is through Scripture that God reveals Himself and His will for humanity. A believer is one who does not pick and choose what to believe based on personal understanding but accepts all that God has said through His inspired Word. The sermon points out that true believers confront and acknowledge their sins as exposed by Scripture, desiring truth at all costs. This reliance on God's Word strengthens faith and fosters a deeper relationship with Christ. As noted in Matthew 4:4, man lives by every word that proceeds from the mouth of God, and this underscores the necessity of fully trusting God's teachings.
