How do we know that God speaks through His Word?

The assurance that God speaks through His Word is found in numerous scriptural accounts that highlight His active engagement with humanity. For instance, in John 6:37, Jesus promises that all whom the Father gives Him will come to Him, indicating that God's call is effective and powerful. The Word of God is not just a written text; it is living and active, as stated in Hebrews 4:12, and it is specifically designed to produce faith and repentance in the hearts of the elect. Only by God’s initiative do we come to understand His truth, as Romans 10:17 states that faith comes by hearing the Word of God.
