Jesus said He had `declared unto them your name`.

Who is the `your` in this statement? -> His HolySpiritFather

What is the `name` in this statement? -> Jesus

How did Jesus declare? -> He is the express image of His HolySpiritFather

So, Jesus came to reveal the Truth about `God` who is our HeavenlyFather, who is His HolySpirit who is love who will be in us who receive Him by His name, Jesus.
