How do we know that preaching is the primary means of grace?

The evidence for preaching as the primary means of grace is firmly rooted in Scripture. In 1 Peter 1:23, it is stated that believers are born again through the preaching of the imperishable Word of God. This underscores that the gospel is not merely to be read or heard informally; it is to be heralded from the pulpit, making the preaching of God's Word central to church life. Furthermore, throughout the Book of Acts, we find that preaching was paramount in the establishment and growth of the early church. Peter's sermon at Pentecost, which resulted in 3,000 conversions, exemplifies this principle. Thus, through both biblical teaching and historical example, preaching is affirmed as God's chosen instrument for accomplishing His redemptive purposes.
