Yes, there is no universal salvation. You’re not saved just belonging to a group. To each is given the Holy Spirit. The Bereans were commended for “searching the scriptures daily” to see if the things they were told were true.
>>Are your results/religious beliefs then binding for all Christians or only for you?<<
Binding? Only Catholics would use that term. Those of us who are set free from bindings by Christ are “free indeed”. For those who truly seek God’s will the Holy Spirit, if asked in earnest, will be given the guidance they each need.
>>If every Christian is tasked the same as you (above), when others arrive at different results,<<
There is only one Holy Spirit and will lead each to all truth if He is asked with a pure heart. Put aside personal prejudices and preconceived ideas. No human can have your interest at heart more then you and the Holy Spirit do. Trust someone else to interpret for you and you will get what they get.
God will never turn down a person who earnestly seeks Him and His will. Seek the will of some human somewhere and there is no promise.
Binding?
Meaning apply, restrict to, limited to, encompassed within... You could either believe your results, say concerning salvation, apply to or are true for every Christian or not. If so, then we could say others are bound by your results. It is whether they are "free indeed" to arrive at different conclusions and still be valid in your view.
I'm still not sure what your answer is to this question; yes? no?
There is only one Holy Spirit and will lead each to all truth…
The question was when others arrive at different results, what standard or basis is used to determine which is correct. If you are saying the Holy Spirit, how is this done in practice? What if both do as you say and still arrive at different results?
Trust someone else to interpret for you and you will get what they get.
Is the measure of an interpretation that it is yours? Or that it is true? On what basis or standard is this determined?
