That is why God offers it to all. Titus 2:11 "For the grace of God that bringeth salvation hath appeared to all men," Isaiah records God as saying, "Turn to me and be saved, all the ends of the earth! For I am God, and there is no other."(Is 45:22) The author of Hebrews said it was for everyone. "
Hebrews 2:9
But we see him who for a little while was made lower than the angels, namely Jesus, crowned with glory and honor because of the suffering of death, so that by the grace of God he might taste death for everyone.
So as you can see, Grace is given to all who will receive it. It won't be given to those who do not want it, for that would be forcing them, and then it would no longer be a gift.
God gave the gift to the world, for He loved the world. (See John 3:16.) He died for the whole world. (see 1 John 2:2) But a gift ceases to be a gift if it is not accepted, for a gift must be given and received. It is available to all, but not everyone avails themselves of it.
They could have taken it from God's hand by faith, but they would not. John Calvin had a mean god; thus, he became mean to those who opposed his theology. The damnation of any man comes at their own hands; by their own choice, don't lay that on God who emptied heaven to save them.
You took those scriptures completely out of their context. This conversation was about rich people having a difficult time with salvation. It was not a general teaching about salvation.
16 Just then a man came up to Jesus and asked, “Teacher, what good thing must I do to get eternal life?”
17 “Why do you ask me about what is good?” Jesus replied. “There is only One who is good. If you want to enter life, keep the commandments.”
18 “Which ones?” he inquired.
Jesus replied, “‘You shall not murder, you shall not commit adultery, you shall not steal, you shall not give false testimony, 19 honor your father and mother,’[c] and ‘love your neighbor as yourself.’[d]”
20 “All these I have kept,” the young man said. “What do I still lack?”
21 Jesus answered, “If you want to be perfect, go, sell your possessions and give to the poor, and you will have treasure in heaven. Then come, follow me.”
22 When the young man heard this, he went away sad, because he had great wealth.
23 Then Jesus said to his disciples, “Truly I tell you, it is hard for someone who is rich to enter the kingdom of heaven. 24 Again I tell you, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God.”
25 When the disciples heard this, they were greatly astonished and asked, “Who then can be saved?”
26 Jesus looked at them and said, “With man this is impossible, but with God all things are possible.”
This was said to His disciples. And He did choose them, yet one was a devil.
This is true. God knows who will respond and choose Him. His grace calls them. That same call goes out to the whole world, but the proud have no ears to hear it because they will not humble themselves in the sight of God. All men can access the call, but too many refuse to listen.
God knew who would hear it; in that sense, it was a call to them: His Sheep. But the offer is still there for all men. The seed is still cast on the hardened path.
Because John Calvin misunderstood and misapplied selected texts from the bible does not mean that we should.
