20 and we have known that the Son of God is come, and hath given us a mind, that we may 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 the life age-during!
20
We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true by being in his Son Jesus Christ. He is the true God and eternal life.
