How do we know the Five Points of Dordrecht is true?

The Five Points of Dordrecht, also known as TULIP, articulate key aspects of Reformed theology which align with various scriptural teachings. For instance, the doctrines emphasize total depravity, unconditional election, limited atonement, irresistible grace, and perseverance of the saints. Each point is founded on biblical texts that substantiate God's sovereignty in the act of salvation. Passages such as Ephesians 2:1-5 and John 10:27-30 reveal God's initiative and sustaining power in the salvation of His people, proving the validity of these points as they affirm the Scriptures' teachings about God's mercy and grace towards the elect.
