How does God call His people according to His purpose?

God's calling is described as a holy calling not based on our works, but according to His own purpose and grace (2 Timothy 1:9). This means that before the foundation of the world, God identified those He would call to Himself—those whom He foreknew and predestined. His calling results in a new heart and a genuine love for Him, transforming us into people who respond to His grace. This calling is sure and effective, meaning that all whom God calls will ultimately come to faith in Christ, confirming that God's purpose will be fulfilled without fail.
