Philippians 1:28-29
28 And in nothing terrified by your adversaries: which is to them an evident token of perdition, but to you of salvation, and that of God.
29 For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake
Your claim does not align with the verb tense used for the word "believe" in Phil 1:29.
"salvation itself is in view" ... "unto you it is given ... to believe on Him".
Again, Phil 1:29 is written to born again believers ... salvation had already been granted ... salvation occurred sometime in the past for these believers.
the word "believe" in vs 29 is in the present tense ... so it is not salvation which is in view ... to believe on Him after we are born again as we go through times of trial and suffering ... keep looking to Him as He is the One Who will guide us through ... looking unto Jesus the author and finisher of our faith (Heb 12:2) ... yes, He will help us in our time of need.
Salvation is not in view in Phil 1:29.
What is in view is what has already been explained to you ... praying God gives increase ...
