How does God call His people to Himself?

According to Reformed theology, God calls His elect through the preaching of the gospel, a process illustrated in Jeremiah 3:14 and revealed in the ministry of John the Baptist. He calls one from a city and two from a family to bring them to Himself. This divine call is not merely an invitation but a powerful work of God, whereby His Spirit convicts and transforms the heart of the sinner, enabling them to respond in faith. Paul also emphasizes this in 2 Corinthians 5:20, where believers are depicted as ambassadors for Christ. This means that the message they proclaim is the very call of God, reconciling sinners to Himself through Christ's finished work.
