That post is based on two non-sequitur arguments
- That since the apostles prayed addressing Jesus, Jesus is God.
- That since Jesus knows the heart of all men, Jesus is God.
FIRST NON-SEQUITUR: Since the apostles prayed addressing Jesus, Jesus is God.
If the apostles indeed addressed Jesus in their prayer, it was the most natural thing to do in that context, as they thought that since Jesus had chosen his 12 apostles, He could guide them, from heaven, to choose whom would replace Judas. Baha'is also sometimes address Baha'u'llah and I have addressed my deceased father. Catholics address Virgin Mary. From that it does not follow (
non-sequitur) that the apostles thought Jesus was God, or that Baha'is think Baha'u'llah is God, that I think my deceased father is God, or that Catholics believe Virgin Mary is God.
We have clear evidence that the resurrected Jesus taught their apostles that Jesus God was The Father, the same God that his Jewish disciples believed (John 20:17). We have clear evidence that after the pouring of the Holy Spirit in Pentecost, the apostles continued to believe that Jesus was NOT the God of Israel, but the son of the God of Israel (Acts 3:13)
SECOND NON-SEQUITUR: Since Jesus knows the heart of all men, Jesus is God.
Jesus made very clear, over and over and over, that all his powers derived from God, His Father. Those powers were not inherent, but conferred.
So, Jesus could examine the hearts of any man in any circumstance to accomplish his mission, without being God Himself.... just in the same way he is said to have calmed down the storm or forgiven sins.
But
it is God, the God of Abraham, Isaac and Jacob, the Father of Jesus, the Only True God, the ultimate source of all heart-knowing abilities.
This teaching was revealed many times in the Holy Hebraic Scriptures.
Jesus knew that, and that's why He addressed the Pharisees: "Y
ou are those who justify yourselves before men, but God knows your hearts. For that which is highly esteemed before men is an abomination before God." (Luke 16:15). This "God" is obviously the Only God his audience knew, YHWH, but if we want it more specific, Jesus said
"And your Father who sees in secret will reward you openly." (Mat 6:18) Every time Jesus says "God" He refers to the Father, the Only and True God, and NOT to himself (John 17:1-3).
The apostles knew that God, the God of Israel, knows the hearts (Acts 15:8) "
After much disputing, Peter rose up and said to them, “Brothers, you know that some time ago God decided among us, that by my mouth the Gentiles should hear the word of the gospel and believe. God, who knows the heart, approved of them, giving them the Holy Spirit just as He did to us." And again, every time the Jewish apostles said "God", they refered to the only God they knew: the God of Abraham, Isaac and Jacob, who is NOT Jesus.
The author of 1 John also makes us know that that it is God the source of All Knowing power:
For if our heart condemns us, God is greater than our heart and knows everything. (1 John 3:20).
Who is this God, in the mind of the author? The Father. For him, as for any single writer of an inspired text in the New Testament, "God" means "The Father": "
Whoever believes that Jesus is the Christ is born of God, and everyone who loves the Father loves the one born of the Father." (1 John 5:1)
