How do we know that the doctrine of effectual calling is true?

The doctrine of effectual calling is rooted in the belief that God calls specific individuals to salvation in His divine purpose. Romans 9:11 highlights this by stating that God's purpose in election stands regardless of human actions. Furthermore, 2 Timothy 1:9 states, 'He saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace.' This portrays that God's calling is not contingent on human merit but grace, affirming that those whom He calls will indeed respond to this call. The transformational aspect of this calling is evident in the lives of believers who perceive it as a direct interaction with God's grace.
