I attempt to explain all scriptures, because I believe that scripture proves scripture if they all harmonize. I do not understand all scriptures, but I am confident that they should all harmonize. I believe that the scriptures overwhelmingly support limited atonement, and eternal deliverance by God's sovereign grace, without the help of mankind.(Eph 2:8-9) They affirm that God elected a people before the foundation of the world, Eph 1, and God predetermined that they would be adopted as his children by the payment of Jesus's sacrifice on the cross.
God's elect children are those, in John 6:37, that he says SHALL come to him, and that he would not lose any of them in verse 39. I understand that those that come to him are those that he gave the new birth to in Eph 2, while they were still spiritually dead, as explained in 1 Cor 2:14. Christ died for the world of believers (his elect) and the only ones that SHALL come to him, and they were the only ones that Jesus's Father gave him to die for. Scripture will prove scripture, if you use them in harmony with each other, and not ignore any of them.
The vast majority of society in Jesus's days on earth thought his doctrine was crazy, and it remains the same in this day and time. This is prophecy.
