Jim Osman examines 2 Peter 1:19-21 to reveal why Scripture stands as a sure word for believers. Building on the Protestant Reformation principle of Sola Scriptura, Osman demonstrates that Scripture's authority rests not on human interpretation or church tradition, but on its divine origin through the Holy Spirit. The exposition shows that Scripture's meaning is determined by God Himself, not by individual readers or ecclesiastical authorities. Peter contrasts true prophetic revelation with false prophecy, emphasizing that no prophecy came by human will but by men moved by the Holy Spirit who spoke from God. This ensures Scripture is inspired, inerrant, and authoritative.

Unlike modern charismatic movements that claim to teach prophetic skills, true biblical prophecy originated entirely from God's initiative, not human desire or training. Osman challenges believers to recognize Scripture as a sure word—God's living voice speaking directly to them today. The passage affirms that what God intended to communicate through the prophets is precisely what was written, making Scripture trustworthy, dependable, and sufficient for life and godliness.
