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?
Looking for legalisms where there should be none is religion. With a bottom line of the simple gospel of believe on the Lord Jesus and you will be saved and your house and the understanding that nothing I can do will be good enough and Jesus is the one doing the good works through me ask and it shall be given, seek and you will find the truth with the help of the Holy Spirit. Looking for carnal answers will get you no where. Trying our own understanding is futile. Trust in Him alone and He will guide your footsteps. Trust totally in Him and He will never let you down.
