Hearing that did not compel those Jesus told to "stop grumbling" in John 6:43 ... so there must be something MORE involved. "WHAT" that something is falls into the realm of human speculation
Not at all, because we know, some people were just tagging along. Not everyone grumbled, or left because the Messiah sad something they didn't understand at the time.
Can you see the point, how people, from reading and learning the OT scriptures, of how gracious, how loving, how merciful God is.....are "drawn to Jesus", because the same attribues of his Father are pouring out of him? No different than saying,
If God were your Father, ye would love me Jn.8:42
unless you know of a verse where God says "Some people believe and other's don't because ..." (and I have overlooked that verse with all my readings).
[I suspect that information falls into "nunya" ... "
none of your business. - GOD".]
The Bible plainly says why some believe and some don't, but the following reasons can all be reduced to the reason being pride, and ones decision to hang onto it, or let it go. To start, our Father wants to reason with sinners,
Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool. If ye be willing and obedient, ye shall eat the good of the land: But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken
it. Isa.1:18-20
I think the very famous Calvanist argument about how God "hardened Pharaohs' heart", is a good example of how God reasons with sinners. Here's the key,
For he saith to Moses, I will have mercy on whom will have mercy, and I will have compassion on whom I will have compassion. Rom.9:15
Here are the people God has mercy on,
to
him that is poor and of a contrite spirit, and trembleth at my word. Isa.66:2
So then
it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy. Rom.9:16
In other words, it's not because of anything but Gods' righteousness, who is Christ, who showed us how patient he is with all sinner.....like Pharaoh?
For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth. Rom.9:17
What purpoe was that?
He, that being often reproved hardeneth
his neck, shall suddenly be destroyed, and that without remedy. Pro.29:1
Now the Calvanist view, is that God didn't want Pharaoh to repent. God put the whammy on Pharaoh so he couldn't repent.
What you need to understand, is that God did no more to harden Pharaohs heart, than send Moses to him...with a demand. Pharaoh might even have laughed, as he was revered as a god.
Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will? Rom.9:19
The Calvanist view is that it was Gods' will to destroy Pharaoh, but try to think about the reason, the reproval, the patience, etc, which God shows towards all sinners,
Nay but, O man,who art thou that repliest against God? Shall the thing formed say to him that formed
it, Why hast thou made me thus? Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour? Rom.9:20-21
I have previously on this forum directed Calvanists to Jer.18, which explains how God as potter forms the clay, but no one
commented on truth in Jer.18. Dead silence.
Other than a mistake in translation, where the scholars made a erred in Rom.9:22, by inserting the word "What" at the beginning of that verse, turning it into a question, instead of the word"if", which the verse actually begins with and means Paul is making a case. He's saying if God was willing to make his power known....
endured with lonsuffering the vessels of wrath (simply sinners) fitted to destruction (simply headed that way),
Now his conclusion, proving his points before),
What shall we say then? That the Gentiles, which followed not after righteousness,have attained to righteousness, even the righteousness which is of faith. Rom.9:30
Eight verses later (Rom.9:22-30) Pauls conclusion is that God makes his power known by enduring vessels on the road to destruction, which is what Jesus did,
Christ the power of God, a 1Cor.1:24
