How do we know that salvation is through believing the word of God?

In Scripture, especially in James 1:18, it is emphasized that we are born again by the word of truth. This process of regeneration is initiated by God, who, in His sovereignty, uses the proclamation of His word to awaken faith in the hearts of the elect. The gospel conveys the reality of our depravity and the necessity of redemption through Christ, affirming that true belief entails both acknowledgment of our need for a Savior and reliance on Christ's finished work. Therefore, faith in the gospel as God’s means of saving us is foundational to our salvation.
