Hopefully making theology simpler to understand! (2 Corinthians 1:12)

Whoever confesses that Jesus is the Son of God, God abides in him, and he in God.
1 John 4:15, ESV

If confess and believe that Jesus is the Son of God, God incarnate – God in the flesh, fully God and fully man – and that He lived a perfect life to die as our atonement on the cross and then rise back to life …

… you are saved. God dwells in you through the Holy Spirit to the glory of the Father.
