I would like you just expound a little on these passages without throwing a bunch of other passages in. Please do not assume I am using them to argue I simply would just like to see how you interpret them. but before that, why does Paul thank God for the faith of the people he is writing to if God had nothing to do with their believing?
Romans 8:30 "And these whom He predestined, He also called; and these whom He called, He also justified; and these whom He justified, He also glorified."
Jude 1:1 "... To those who are called, beloved in God the Father, and kept for Jesus Christ"
1 Thessalonians 1:5, "for our gospel did not come to you in word only, but also in power and in the Holy Spirit and with full conviction."
Romans 11:29 "for the gifts and the calling of God are irrevocable"
I will attempt to answer these verses you asked about. First, Rom 8:30. I notice you excluded verse 29, let's look at that.
Rom 8:29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
Before predestination comes foreknowledge. So there is something God foreknew that caused him to predestinate these persons. I personally believe that God knew who would believe on Jesus, and I have shown many verses to support this as you know, so I won't repeat them (but I can if you feel it is necessary).
Second, what does it say we are predestined for? To be saved? No. It says to be conformed to the image of his Son. And no non-Cal would disagree that we are called. Coming to God wasn't our invention, it was 100% of God and his will. But Jesus called many who are not chosen or elect.
Matt 22:14 For many are called, but few are chosen.
I have seen you say several times that if God calls or draws a man that they must be saved. You are in error here, Jesus said many are called, but few chosen. Just because Jesus calls you does not mean you will come. But those who do come were called. This seems to be difficult for you to grasp.
I will answer the other verses later.
