The effectual call is God’s personal and powerful drawing of sinners to Himself, initiating a response of faith that leads to salvation. Jesus emphasized that no one can come to Him unless drawn by the Father. This call is not a mere invitation but a decisive action of God, working in the hearts of people to enable repentance and belief. The effectual call demonstrates that salvation begins entirely with God’s initiative, ensuring that His purposes in calling His people are fully accomplished.
The general call of the gospel that everyone has the capability of hearing is different from the effectual call that leads to salvation. Jesus stated, "For many are called, but few are chosen" (Matthew 22:14). In this verse Jesus is saying that few have experienced the effectual call, although many have heard the gospel message. Romans 1:6 also teaches the effectual call when Paul writes to those "who are called to belong to Jesus Christ." Acts 16:14 alludes to the effectual call when Luke describes Lydia's heart being opened by the Lord so she could respond to Paul's message. These examples show that God's calling is a definitive action toward those He saves. He chose His children in Christ, "before the foundation of the world, that we should be holy and blameless before him" (Ephesians 1:4).
No one can turn to God without God first impressing Himself on them. Everyone is capable of hearing the gospel (John 3:16), but because of humanity's sinful nature no one turns to God apart from His effectual call.
