‘Whoever will confess that Jesus is the Son of God, God abides in him, and he in God.'
God's salvation is only effective through His Son. Each one who truly confesses Jesus as God's Son, and as the Saviour of the world, believes in the fact that the only Son became flesh in the man Jesus and dwelt among us, and makes that confession as a response of faith in the light of all He has done for us in dying for us. Then as a result of this true faith he has God abiding in him, and himself abides in God. So salvation is through faith, and love for the brethren is one of the outwards signs of the reality of that faith and of our experience of God's love.
