God calls whoever to believe in His only begotten Son (John 3:16). The call comes through hearing or reading the gospel. God's effective call saves us, as we receive the engrafted word (James 1:21). The Holy Spirit convicts the world of unbelief (John 16:7-11). God's call is effective, when faith comes through hearing the Word of God (Romans 10:17).
God's effective call is when we believe on the Lord Jesus Christ (Acts 16:31). God commands all people everywhere without exception to repent (Acts 17:30). The benevolent will of God's grace common to all is for sinners to turn away from the old life and receive new life in Christ. God has no pleasure in the death of the wicked (Ezekiel 33:11). None are turned away who truly come by faith to Christ (John 6:37).
God's effective call is in all who believe the gospel of Christ (1 Corinthians 15:1-4). Some may hear the gospel and even be convicted by the Holy Spirit without being convinced to believe in Christ (John 16:7-11). However, God's effective call goes beyond conviction. The Holy Spirit enables us to confess that Jesus Christ is Lord (1 Corinthians 12:3).
God's effective call changes our hearts through the gospel of Christ (Acts 16:14). That's when we are awakened to the truth of the gospel. Then, we are willing to receive and believe the Lord Jesus Christ (John 1:11-13). That's when the gospel comes to us not in word only, but with power and much assurance through the Holy Spirit (1 Thessalonians 1:5). That's God's effective call.
