How do we know God calls His people to Himself?

The assurance of God's calling comes from understanding His sovereign grace and His divine purpose in salvation. Scripture reveals that God calls individuals from darkness to light, often in ways beyond human comprehension. The transformation seen in figures like Saul of Tarsus is emblematic of how God actively chooses and awakens His people. This calling is not dependent on human merit or understanding but rests solely on God's mercy and will, demonstrating His sovereignty over salvation.
