Therefore, as for you, let that remain in you which you heard from the beginning. If that which you heard from the beginning remains in you, you also will remain in the Son, and in the Father.
So in the beginning of their faith they were taught that Jesus Christ was the Son of God. He came to be the Savior of the world. Now hold fast to that, let it abide in you, for you will continue both in the Son and in the Father.
