Thank you for sharing this experience, yes it is great how God work.

It is really difficult to understand the three persons of God, but as you say we must just believe. Another great verse indicating that Jesus was there from the beginning is John 1, as we know the Word is Jesus.

1)In the beginning the Word already existed; the Word was with God, and the Word was God.
2)From the very beginning the Word was with God.
3)Through him God made all things; not one thing in all creation was made without him

Thanks for the very nice reply.
