Who `sent` Jesus? ->His HolySpirit who impregnated Mary.

So, we are to believe on Him who sent Jesus? What does that mean? It means that we are to believe that the HolySpiritFather is manifested InChrist Jesus so that -> the Words Jesus spoke -> the Works Jesus did
are the Words and Works of His HolySpiritFather.

Accordingly, what we believe about Christ Jesus is that He is the express image of God, the HolySpiritFather making Him His own Father. Father = Son = HolySpirit = God who is SpiritSoulAndBody in Christ Jesus.

Hearing, believing, receiving and doing the Word of the Lord is the expectation of the Lord for each of us.
When we do so we enter into everlasting life.
We are forever delivered from condemnation.
