I understand your question but in my opinion we need to remember two things.
Even our faith is a gift from God. God does not give imperfect gifts.
(ISV) For by the grace given to me I ask every one of you not to think of yourself more highly than you should think, rather to think of yourself with sober judgment on the measure of faith that God has assigned each of you.

(LITV) For through the grace which is given to me, I say to everyone being among you, not to have high thoughts beyond what is right to think. But set your mind to be right-minded, even as God divided a measure of faith to each.
(MKJV) For I say, through the grace given to me, to every one who is among you, not to think of himself more highly than he ought to think. But set your mind to be right-minded, even as God has dealt to every man the measure of faith.

(KJV) Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference
(LITV) even the righteousness of God through faith of Jesus Christ toward all and upon all those believing; for there is no difference,
(MKJV) even the righteousness of God through the faith of Jesus Christ, toward all and upon all those who believe. For there is no difference,
