Yes, but this assurance is never independent of what we do, see, for example, how the saving faith of which Jesus speaks in John 5:24 coexists with the judgement by the works in verse 29.
Understand, no one who is Catholic disagrees that faith is central to our salvation, — the disagreement is that the faith without works is dead, as the Scripture teaches, and theat the judgement is by the works, as the Scripture also teaches.
Joh 5:28 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice,
Joh 5:29 And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
Really??? Who's in the grave that will be listening to God??? Do you Catholics hang around in the graves when you pass on???
But truly I was not venturing into the Predestination v. Free Will debate. I was presenting God's blessed assurance from Scripture.
Concerning the Predestination v. Free Will debate I would say that both are true. Scriptures reveal Predestination in Prophecy and Free Will in Commandments.
A thing is True because God says it. Whether or not it is logical or reasonable to us mere mortals is irrelevant.
For he spake, and it was [done]; he commanded, and it stood fast. Psalms 33:9
The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. [There is] no speech nor language, [where] their voice is not heard. Psalms 19:1-3
To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out. And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice. And a stranger will they not follow, but will flee from him: for they know not the voice of strangers. - John 10:3-5
My Father, which gave [them] me, is greater than all; and no [man] is able to pluck [them] out of my Father's hand. John 10:29
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. - Galatians 2:20
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. - Romans 8:9
