In the above, you summarize nicely one of the primary pitfalls. Each of your sentences begins with the word "I". The truly humble person does not think in these terms but rather places the credit outside himself.
The truly humble words your comments differently because in true humility the goal is never about him/her.
If I may rephrase.....
I know which religion is right.
Dear God thank you for showing me the path by which to serve you in Love.
I understand what the scriptures mean.
Father guide me in the proper understanding of your Holy Word and send me good confessors and councilors.
I can apply the scriptures in daily life.
O Lord, help me to apply your word, your will and your love in all of my actions daily.
I can wield power in the name of God.
Father, whatever influence I have is yours, guide me to use it solely in love and for your Glory
I am humble.
Oh Lord keep me humble.
You have not really changed anything!!
The speaker of your sentences is still presuming himself to know which path is The Right One:
Dear God thank you for showing me the path by which to serve you in Love.
How does the speaker know that he is on the "path by which he can serve God in love"?
He is simply sure of his own judgment that he is on the right path!
Thus, no different than saying "I know which religion is right."
I understand what the scriptures mean.
Father guide me in the proper understanding of your Holy Word and send me good confessors and councilors.
And yet it is your supposedly humble speaker who will decide whether he understands His Holy Word or not.
I can apply the scriptures in daily life.
O Lord, help me to apply your word, your will and your love in all of my actions daily.
Says your supposedly humble speaker - but then nevertheless abides by his own discernment of what is God's word and what is not.
I can wield power in the name of God.
Father, whatever influence I have is yours, guide me to use it solely in love and for your Glory
Big words, that just try to hide that he is acting by his own discernment anyway.
I am humble.
Oh Lord keep me humble.
What does that matter, if eventually, it is your supposedly humble speaker who decides whether he is humble or not?!
The humble recognizes that "The Lord Gives and the Lord takes away - Blessed be the name of the Lord. (Job 1:21)
And yet, your supposedly humble speaker here still presumes himself to know which is which.
Wrapping it all up in nice, modest-sounding words does not do away with the epistemological problems of discerning between what is from God and what is one's own or other people's stance.
The humble seeks the council of good and holy priests and people committed to God, in Love and to all things good.
And yet this supposedly humble person is the one who decides - and then abides by this decision - who the "the council of good and holy priests and people committed to God, in Love and to all things good" is, and who is not such a council.
The humble recognizes that his true wealth and/or power lies, not in his bank balance, but in the number of people helped, the number employed, the good that is returned to the community and that, just as God's Love flows through him as a mere agent, any accolades that come to him need to flow through him to God in thanksgiving.
Again, it is still your supposedly humble speaker who decides - and then abides by his decision - whether he actually helped someone or not. Disregarding whether those people whom he claims to have helped, actually were helped.
It is still your supposedly humble speaker who decides - and then abides by his decision - whether good was returned to the community.
Etc.
Bottomline: Your seemingly modest formulations do not actually change anything.
The person clearly making I-statements is at least being straightforward about it all.
Your supposedly humble speaker wraps himself in big words, professing modesty, but is in actually the same epistemic egotist as the one making I-statements.
