Gino, this is a recipe for deception: "if we asked God to speak to us we should expect him to answer. Whatever was the first thing that came to our minds in that moment... must be God." I suppose you know that the "fiery darts of the wicked [one]" (Eph 6:16) may well be lies and counterfeits whispered to your mind.
You said, re what you were taught, "Basically the most genuine way to get to know God for them is outside of scripture bc this shows a relationship with him." In truth, this shows an ignorance of Scripture, and is a falsehood.
In John 6:63 NKJV, Jesus says, "It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life."
It is by knowing His word that we learn to know Him, His heart, His mind, what grieves Him, what delights Him. The Holy Spirit regularly reminds us of Jesus' sayings: "the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you" (John 14:26 KJV).

Here's a help in prayer I wrote out for souls in my church (and for myself!)
HELP IN PRAYER
It is vital for us to have the blessings of a consistent prayer life, a “beach-head” against the forces of the world, the flesh, and the devil. I myself sometimes find that I have no “ease” or “sense of spiritual reality” in my praying—so I rely at such times solely on the word of God, on His promises—as therein reality is made known, and I can function in productive prayer simply by sheer faith in His word. A few such promises:
Matt 11:28-30 Come to Me, all you that labor and are heavy laden, and I will give you rest. Take My yoke upon you, and learn of Me, for I am meek and lowly in heart; and you shall find rest for your souls. For My yoke is easy, and My burden is light.
John 6:37 the one who comes to Me I will in no wise cast out
James 4:8 Draw nigh to God, and He will draw nigh to you
Matt 28:20 I am with you always, even unto the end of the world
Heb 13:5 I will never leave you, nor forsake you
Isa 41:10 Fear thou not; for I am with thee: be not dismayed; for I am thy God: I will strengthen thee; yea, I will help thee; yea, I will uphold thee with the right hand of my righteousness.
1 Pet 5:7 Casting all your care upon Him, for He cares for you
Isa 54:10 my kindness shall not depart from thee…neither the covenant of my peace
Jer 31:3 I have loved thee with an everlasting love: therefore with lovingkindness have I drawn thee
Isa 66:2 on this one will I look: who is poor and of a contrite spirit, who trembles at My word
Isa 57:15 … to revive the spirit of the humble, and to revive the heart of the contrite ones
Prov 15:8, 29 the prayer of the upright is His delight…He hears the prayer of the righteous
Psalm 143:8 Cause me to hear Thy lovingkindness in the morning; for in thee do I trust; cause me to know the way wherein I should walk, for I lift up my soul unto thee.
1 Pet 3:12 the eyes of the Lord are over the righteous, and his ears are open unto their prayers
Psalm 46:1 God is our refuge and strength, a very present help in trouble.
Psalm 73:26, 23 My flesh and my heart faileth: but God is the strength of my heart, and my portion for ever…I am continually with You; You hold me by my right hand
John 8:12 I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
2 Cor 12:9 My grace is sufficient for thee: for my strength is made perfect in weakness.
Phil 4:6, 7 Be careful / anxious for nothing; but in everything by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passes all understanding, shall keep your hearts and minds through Christ Jesus.
Isa 26:3, 4 Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusts in thee. Trust ye in the LORD for ever: for in the LORD JEHOVAH is everlasting strength
Prov 23:15 My son, if thine heart be wise, my heart shall rejoice, even mine (cf v. 24)
And when this happens (as it does on occasion) it may be well with us:
Isa 50:10 Who is among you that feareth the LORD, that obeyeth the voice of his servant, that walketh in darkness, and hath no light? let him trust in the name of the LORD, and stay upon his God.
