I think you’ve articulated a question that more people should be asking out loud.
The ideas many Christians assume with this kind of stuff may not be 100% accurate regarding how spiritual and spiritual-ish powers operate. I am no expert but here are 3 or 4 initial thoughts I’ve borrowed from the bible to account for some of the would-be-issues you require clarity for on the subject you’ve introduced. Certainly a book could be written, but these are several take off points to get you pondering and studying in a decent direction:
Thought number 1:
Consider this: Giftings and miracles, even “angles of light” and supposed “words from the lord” aren’t always from the true and living God. “Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?” Matt 7:22
Thought number 2:
Remember the story of Baalam and his talking ass? Baalam was known to have some kind of line to power in connection with blessing and cursings as it were… And although Baalam failed to obey God’s command to not curse Israel, Baalam set out to do it anyhow. The story shows us that God blocked Baalam’s path with an angle holding a flaming sword rather than dis-enabling Baalam’s aparrent gifting when he dared to go out and curse Israel at the king of Moab’s request:
“Come now therefore, I pray thee, curse me this people; for they are too mighty for me: peradventure I shall prevail, that we may smite them, and that I may drive them out of the land: for I wot that he whom thou blessest is blessed, and he whom thou cursest is cursed” Num 22:6
Thought number 3:
It seems that the gifts and giftings of God are not just given to Christians. For starters, the rain falls on both the just and the unjust (Matthew 5:45) … Also note that God uses his goodness (presumably gifts and blessings) to lead men to repentance (Romans 2:4). Those who give God the glory for these things and honor Him accordingly, respond not only to the gospel, but they honor Him with thankfulness for all He’s done and given to them. (see Romans 1) “Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened” (Rom 1:21)
Thought number 4
Regarding the guidance you get from your “gut”. The bible gives some very important instruction about this… From what I understand, the biblical name for what you’re referring to by this, is your “reins”: “I will bless the LORD, who hath given me counsel: my reins also instruct me in the night seasons.” (Psa16:7)
For your conveinience you can confirm this and gain understanding of it it by looking up the following and taking a look at the context 
His archers compass me round about, he cleaveth my reins asunder, and doth not spare; he poureth out my gall upon the ground. (Job16:13) | Whom I shall see for myself, and mine eyes shall behold, and not another; though my reins be consumed within me. (Job19:27) | Oh let the wickedness of the wicked come to an end; but establish the just: for the righteous God trieth the hearts and reins. (Psa7:9) | I will bless the LORD, who hath given me counsel: my reins also instruct me in the night seasons. (Psa16:7) | Examine me, O LORD, and prove me; try my reins and my heart. (Psa26:2) | Thus my heart was grieved, and I was pricked in my reins. (Psa73:21) | For thou hast possessed my reins: thou hast covered me in my mother’s womb. (Psa139:13) | Yea, my reins shall rejoice, when thy lips speak right things. (Prv23:16) | And righteousness shall be the girdle of his loins, and faithfulness the girdle of his reins. (Isa11:5) | But, O LORD of hosts, that judgest righteously, that triest the reins and the heart, let me see thy vengeance on them: for unto thee have I revealed my cause. (Jer11:20) | Thou hast planted them, yea, they have taken root: they grow, yea, they bring forth fruit: thou art near in their mouth, and far from their reins. (Jer12:2) | I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings. (Jer17:10) | But, O LORD of hosts, that triest the righteous, and seest the reins and the heart, let me see thy vengeance on them: for unto thee have I opened my cause. (Jer20:12) | He hath caused the arrows of his quiver to enter into my reins. (Lam3:13) | And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works. (Rev2:23)
