until we all attain to the unity of the faith and of the knowledge of the Son of God – a mature person, attaining to the measure of Christ’s full stature.
And we have come to know and to believe the love that God has in us. God is love, and the one who resides in love resides in God, and God resides in him.
And we know that the Son of God has come and has given us insight to know him who is true, and we are in him who is true, in his Son Jesus Christ. This one is the true God and eternal life.
