Does this mean God will make believers believe?
No, they believe on their own, but when their hearts are regenerated... born again of the Spirit of God.
Are you saying that God will draw people to believe in Jesus by making His grace so attractive that they can't but accept it, making it irresistible?
No, that because ~ in this regenerative act ~ they are then spiritually alive, are healed of this spiritual blindness, and they then know their sinfulness and their need for Christ redemption to God, Whom they now love. As John says, we love because He first loved us. And this love is far, far more than... a "warm fuzzy feeling." :)
How can you be so confident that every single person God elects will be drawn to God (God's grace)?
Well, it's by the grace of God, meaning fully because of His action toward us. The confidence is that it is God's purpose of election; the people who are God's elect are His elect whom He has purposed to save, and God's purposes cannot be thwarted. So the confidence is in God, not in ourselves.
So Jesus wasn't interested in choosing everyone?
He was interested in doing the will of the Father, and the Father has given certain ones ~ His elect ~ to Jesus, not everyone. As Jesus Himself said, "All that the Father gives Me will come to Me, and whoever comes to Me I will never cast out. For I have come down from heaven, not to do My own will but the will of Him who sent Me. And this is the will of Him who sent Me, that I should lose nothing of all that He has given Me, but raise it up on the last day..."
Even so, though, we know (because we are told in the Bible) that
"God our Savior... desires all people to be saved and to come to the knowledge of the truth" (1 Timothy 2:3-4). So in that sense, the answer to your question would be a resounding 'no.' In the case of salvation, God's desire are not congruous with His purpose; His purpose takes precedence over His desire.
Jesus didn't want everyone to go forth and bear fruit? And Jesus didn't want everyone to ask of the Father in His name, that he may give it them?
Hmmm, well, I'm sure He did, and His outward invitation was given to all without discrimination. But He knew very well that not everyone would, but only those whom the Father had given Him (see above).
So if a person hears about God's mercy and His grace, goes to God and accepts His mercy and His grace in His Son Jesus then God will not cast him out but will give them His grace?
Ah, well, I would say, O2Q, that if that person "goes to God and accepts His mercy and His grace in His Son Jesus," He has
already been the recipient of God's mercy, and thus born again of the Spirit. This is
why he accepts.
So God has chosen some, making His mercy and grace irresistible exclusively to them only.
Well, yes, but you seem to be still misunderstanding this irresistibility, Here is what John Calvin actually wrote/said about this grace of God:
"The statement amounts to this, that we ought not to wonder if many refuse to embrace the Gospel; because no man will ever of himself be able to come to Christ, but God must first approach him by His Spirit; and hence it follows that all are not drawn, but that God bestows this grace on those whom He has elected. True, indeed, as to the kind of drawing, it is not violent, so as to compel men by external force; but still it is a powerful impulse of the Holy Spirit, which makes men willing who formerly were unwilling and reluctant... it is entirely the work of grace and a benefit conferred by it that our heart is changed from a stony one to one of flesh, that our will is made new, and that we, created anew in heart and mind, at length will what we ought to will."
...at some time in the history of mankind God broke down the divide between these people He had formerly chosen/elected and everyone else? So from that point on He had chosen everyone or still only those of the commonwealth of Israel? So God cannot present Himself to those outside the commonwealth of Israel or He can? And if He can, it is only by means of a message sent by a human messenger?
God's Israel was never based on ethnicity. Even in the Old Testament Israel contained some foreigners, foreshadowing the opening of the Gospel to the Gentiles. True Jews really were always those ~ regardless of ethnicity ~ who were/are Jews inwardly, with a circumcision of the
heart, by the
Spirit. And these are God's elect, and together all His Israel, people of the household of God.
I'm trying to get a picture of the God of your understanding. What He can and cannot do. His character. What His interest is in and purpose of His creation.
Everything God does is for His own glory. :) Our chief end, of course, is to glorify Him and enjoy Him forever. :)
Grace and peace to you, O2Q.
