Okay. If you took that verse out of its context of the other verses and ignored every other verse in the Bible that shows that all are equally invited to come to faith in Christ, then you could believe that God predestined people to be called to come to Christ and be justified. Going by my personal experience, it really seemed that way for me. It really did seem that God had chosen me for salvation and worked on me for all that time until I came to the place where i made my decision for Christ.
"Ah ha!" You say. "I got you!" But not so fast!
Because I'm trained in Hermeneutics (the principles of interpreting Scripture), I consider the 10 verses before and the ten after to view the verse in its context. So let's unpack the whole passage in context. For the sake of space, I am quoting 5 verses before and 5 after. I am using the Amplified Bible to make sure the meaning comes out more clearly.
"25 But if we hope for what is still unseen by us, we wait for it with patience and composure.
26 So too the [Holy] Spirit comes to our aid and bears us up in our weakness; for we do not know what prayer to offer nor how to offer it worthily as we ought, but the Spirit Himself goes to meet our supplication and pleads in our behalf with unspeakable yearnings and groanings too deep for utterance.
27 And He Who searches the hearts of men knows what is in the mind of the [Holy] Spirit [what His intent is], because the Spirit intercedes and pleads [before God] in behalf of the saints according to and in harmony with God’s will.
In these verses we see that Paul is talking to those who already are Christian believers. This is seen in his use of "we", "our","us" and "the saints". We also see that the Holy Spirit prays for us according to God's will. This is in harmony with Jesus saying to Peter, "I have prayed for you that your faith fails not." It is also in harmony with the gloried Jesus who intercedes for the saints day and night before the throne of God.
28 We are assured and know that [[j]God being a partner in their labor] all things work together and are [fitting into a plan] for good to and for those who love God and are called according to [His] design and purpose.
Here we see that Paul is assuring us, because the Holy Spirit is praying for us, and that God is our Partner in our efforts to serve Christ and all things work together and fit into His plan for good for those who love God and are called according to His design and purpose. This shows that God has a design and a purpose for mankind and is working alongside the saints to being it to pass.
29 For those whom He foreknew [of whom He was [k]aware and [l]loved beforehand], He also destined from the beginning [foreordaining them] to be molded into the image of His Son [and share inwardly His likeness], that He might become the firstborn among many brethren.
Paul's use of the word "for" is connected with the previous verse and "for that reason" is what is implied. Because God has designed a plan that He is developing for mankind and that the past, present and future are the same in His mind (note: He does not time travel into the past or the future at all, but He knows it), He foreknew and was aware of all those who were going to receive Christ, and loving them, preordained them to be molded into the image of Christ, so that Christ can be the elder Brother of many who have received Him as Saviour.
30 And those whom He thus foreordained, He also called; and those whom He called, He also justified (acquitted, made righteous, putting them into right standing with Himself). And those whom He justified, He also glorified [raising them to a heavenly dignity and condition or state of being].
So we come to the verse you want me to answer:
It is linked to the previous verse by the word "thus". What this means is that God, in his foreknowledge and awareness of those who were to choose for Christ in the future, He preordained them. Note: that there is nothing to say that He preordained anyone else for anything. So the passage does not explain anything about preordaining anyone to hell. The only people Paul says is preordained by God are those who have received Christ, and they were not preordained to receive Christ in the first place, but those who did choose Christ were preordained to be molded into the image of Christ. Paul would have clearly said that the saints were destined and preordained to choose for Christ if that was the case. We don't see that in these two verses. What we do see is Paul plainly showing that the predestination happens AFTER the person chooses Christ, and not before. To say that predestination is involved in people choosing Christ is to add to God's Word something that is not there, and is putting words into Paul's mouth that he never said.
Paul says that those who choose for Christ are "also" called. That means that the calling comes at the same time as the predestination, along with justification and glorification. This shows clearly that a person chooses for Christ, and then he is converted to Christ (called, justified, and glorified). This shows that God foreknew and was aware of those who were going to choose for Christ, and for those He predestined to convert them to Christ.
31 What then shall we say to [all] this? If God is for us, who [can be] against us? [Who can be our foe, if God is on our side?]
32 He who did not withhold or spare [even] His own Son but gave Him up for us all, will He not also with Him freely and graciously give us all [other] things?
33 Who shall bring any charge against God’s elect [when it is] God Who justifies [that is, Who puts us in right relation to Himself? Who shall come forward and accuse or impeach those whom God has chosen? Will God, Who acquits us?]
34 Who is there to condemn [us]? Will Christ Jesus (the Messiah), Who died, or rather Who was raised from the dead, Who is at the right hand of God actually pleading as He intercedes for us?
35 Who shall ever separate us from Christ’s love? Shall suffering and affliction and tribulation? Or calamity and distress? Or persecution or hunger or destitution or peril or sword?
36 Even as it is written, For Thy sake we are put to death all the day long; we are regarded and counted as sheep for the slaughter" (Romans 8:25-35).
The rest of the passage shows the effects that genuine conversion has on us, and doesn't need further explanation.
The passages goes right along with my belief that if we pray for the conversion of sinners, God will answer our prayers and work in them by the Holy Spirit to influence and persuade them to come to Christ. He knows beforehand who will and who won't, but He does not disclose this to us because He wants us to pray for all sinners who come across our path. He wants us to know that every sinner we meet and pray for has the potential and ability to receive Christ.
Therefore, as the result of prayer, the Holy Spirit will give the understanding of the gospel and the information needed to make the choice to receive Christ to every unconverted person, and the only ones who will find themselves in hell will be the ones who will be there because of their willful choice to reject Christ, and not because God preordained them to hell as part of His design for them.
