If we really are in any measure really believers in God and His Son, there some things we really do know and some things we only believe that we know. Herein lies probably the difference between various believers in God and in the various denominations. We are unable to always know which ones are definitely known as opposed to those that are only believed.
I gave you examples of what I would be certain and uncertain, but your last sentence was incoherent and vague.
I hope I never gave the impression that I am sinless, or have pure doctrine, but rather each and everyone ought to stand firm on their convictionsThe individual who never quenches the Holy Spirit will never lack for the right words or the right time to remain silent... The problem is most or even all churches [denominations] regularly teach and practice quenching the Holy Spirit in their services and in their walk with God. As a result when they do go astray they quite often are deluded because they have come to love all of that which they hold out as truth rather than what truth really is. Who has never quenched the Holy Spirit since they first met God? Who has always in every moment and every decision since meeting God has never sinned? Do our past correct actions according to God assure us that we will never make another mistake [sin again]?
I can't speak for you, but that is a swinging door for me. I have spoken when I should not have, and was silent when I should have spoken.And neither you nor I have ever opened our mouth to speak when God really wanted us to remain silent, right?
Knowing Him first starts with being born again, deeper knowledge comes with time, grace, grasping His Word and hard knocks, and yes it is a growth process culminating in Phil 3:10.Yes, Jesus is the Truth, but how well do any one of us know Him? How well do we see Him now... or are we along with Paul when he wrote I Cor 13 still seeing as through a glass darkly? When we step out in faith toward that which we cannot see, is it not best to be sure we are following the Holy Spirit rather than some other spirit? Anyone who ever quenches the Holy Spirit is likely at times to be following some blind leader in a ditch... or?
No but neither do I.We are not speaking of Paul who has already finished course, but you and I who are still walking. When we are blind and/or deaf how far astray can we go it alone supposedly toward Him? Paul did not claim flawless vison here, did he?
No one is claiming to see more clearly than Paul except those who deviate from Scripture."For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known." I Cor 13:12
Are we now seeing more clearly than Paul was when he wrote those words or than he did as he continued his walk toward the end of his course?
I will not use 1Cor 13:12 as an excuse to say 'well we don't see clearly, so can't know or shouldn't strive after what is truth, that is not Paul's intention. The devil would love to confuse truth with error by convincing people that truth is unattainable.
