I know. That's why I'm trying to keep it real and to stay away from some unachievable ideal like "impervious" and withstanding the "vagaries of human opinions".
I am keeping it real... “impervious” was a specific reference, solely, to the tree of life, the Word of God, aka the word of God the holy scripture, or, if you will, Jesus Christ personified in the form of ink and paper (so to speak) the words of which are Spirit, truth, and life...which is the bread of life...which we need to eat to be nourished (believed and absorbed) and so strengthened for the unceasing battle which is waged in our minds.
There is no suggestion that any of us must be “impervious” to the assaults of the enemy against that truth which we have received, for the truth of scripture says otherwise, and so we have good reason to expect that doubts will pierce our minds and that we will be disturbed by them, but for a season only...For the same scripture which forewarns us of our frailties also provides us with our consolation and fortifies us against overwhelming despondency and giving us hope in the midst of our doubts, and in spite of them.
“Though he fall, he shall not be utterly cast down: for the LORD upholdeth him with his hand” - [Psalm 37:24]
“Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand” - [Romans 14:4]
My thoughts above, and in my previous posts, are primarily in reference to this comment from the OP “Guys, I have honestly reached points where I was so discouraged by their commitments that I have drifted from the faith.”
And likewise...“vagaries of human opinions" is a reference, solely, to false doctrine espoused by christians which are the result of the twisting and distortion of scripture, the OP mentioning fellowships associated with arminian doctrines. Those doctrines are essentially “vagaries of human opinions” by default, for the simple reason that they do not conform to the truth of scripture, in regards to accuracy, and rightly dividing the word of God.
Once again, the despondency which assaults our minds and the doubts raised by incessant rebukes and attacks against the gospel, in regards to the truth we have received concerning the doctrines of grace (Calvinism) are to be expected .
“If the world hate you, ye know that it hated me before it hated you” - [John 15:18]
“Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you” - [1 Peter 4:12]
The christian is engaged in a war, that war will be waged in his mind, we can expect to suffer some wounds...but we can be certain of victory...for the word of God is Spirit, truth and life.
Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; And your feet shod with the preparation of the gospel of peace; Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God: Praying always with all prayer and supplication in the Spirit - [Ephesians 6:10-18]
