How do we know effectual calling is true?

The truth of effectual calling is established in Romans 8:30, which outlines a sequence of God's sovereign work in salvation. This verse emphasizes that those whom God has predestined, He also effectually calls, justifies, and ultimately glorifies. The effectual call is distinct from a general call; it is the sovereign work of the Holy Spirit that brings the elect to a true and saving faith in Jesus Christ. With the Holy Spirit's inward call, the chosen are summoned to respond in faith, ensuring that God's purpose in salvation is executed perfectly and without fail.
