The simplest answer is: “Seeing Jesus is seeing God.”
Both the question and answer come from the Word of God in John 14:8-9 when Jesus answered the question asked by Philip, one of His disciples, “Show us the Father (God)” 2,000 thousand years ago.
Philip said, “Lord, show us the Father and that will be enough for us.” Jesus answered: “Don't you know Me, Philip, even after I have been among you such a long time? Anyone who has seen Me has seen the Father. How can you say, “Show us the Father””?
When we see God, no man can live. When we see God in Christ, we live. That’s a great mystery.
Last June 2012, we watched for Venus to cross the Sun. A bit earlier in May, the partial eclipse of the Sun by the Moon occurred and it turned into one of the best photographed astronomical events in history.
I tried to use the homemade device by layering three pairs of sunglasses to view these stunning events, but I failed it.
In both observations, people used a special kind of filtering glass to view one of the best photographed astronomical events in history. Otherwise, they must have blinded their eyes.
Likewise, we can see Invisible God Who is Light only through Jesus Christ Who is Visible God in Flesh.
The Bible says;
“Now to the King eternal, immortal, invisible, the only God, be honor and glory forever and ever. Amen.” (1Timothy 1:17)
“Who alone is Immortal and Who lives in unapproachable light, Whom no one has seen or can see. To him be Honor and Might forever. Amen.” (1Timothy 6:16)
My God and my Lord, Jesus Christ, thank You for showing us the Father, the Holy Spirit in You.
Anyone who has seen You, has seen the Father. Yet we have not seen You, but we believe and rejoice in You, Lord Jesus. Because You told Thomas in John 20:29;
“Because you have seen me, you have believed; blessed are those who have not seen and yet have believed.”
