We know Jesus is the Son of God through God's revelation in Scripture, the witness of the Holy Spirit, and the fulfillment of prophetic texts (1 John 5:20).
The conviction that Jesus is the Son of God comes from multiple sources, primarily from the authoritative witness of Scripture. In John 1:34, John the Baptist testifies, 'I saw and bear record that this is the Son of God,' which aligns with prophecies from the Old Testament, such as Isaiah 9:6, which calls Him 'Mighty God.' Additionally, 1 Timothy 3:16 highlights the mystery of godliness, affirming that God was manifest in the flesh. The work of the Holy Spirit is crucial in revealing the truth about Jesus, as seen in Romans 1, where it states that Jesus was declared to be the Son of God by His resurrection from the dead. The Spirit's work in our hearts confirms our faith in Christ as the true God and eternal life (1 John 5:20).
