How do we know that God calls sinners to Himself?

The assurance that God calls sinners to Himself is evident throughout Scripture, particularly in prophetic texts like Isaiah. In Isaiah 60:3, it states, 'the Gentiles shall come to thy light, and kings to the brightness of thy rising,' revealing God's intention to bring many into His fold. This invitation extends beyond Israel to include the Gentiles, demonstrating God's universal call to redemption. The fulfillment of these prophecies in the New Testament, particularly in the acts of the early church as recorded in Acts, shows God’s sovereign grace in action. He not only calls individuals but empowers them with the Holy Spirit, as seen during the outpouring on Pentecost, where thousands came to faith en masse. Thus, God's calling is both personal and communal, a central tenet of sovereign grace theology.
