Bible passages that help us understand about tongues:

(John 3:3 NKJV) Jesus answered and said to Nicodemus, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”   (v12)”If I’ve told you earthly things and you do not believe, how will you believe if I tell you heavenly things?”

(Mark 10:15 NKJV) “Assuredly, I say to you, whoever does not receive the kingdom of God as a little child will by no means enter it.”

(1Cor 2:14 NKJV) But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned.

(John 14:16-17 TPT) “And I will ask the Father and He will give you another Saviour, the Holy Spirit of truth, who will be to you a friend just like Me -and He will never leave you.”

(John 15:26TPT)” And I will send you the Divine Encourager from the very presence of My Father.  He will come to you, the Spirit of Truth emanating from the Father, and He will speak to you about Me.”

(Matt 6:6 NKJV) “But you, when you pray, go into your room, and when you have shut your door, pray to your Father who is in the secret place; and your Father who sees in secret will reward you openly.”

(Luke 11:11-13 NIV) “Which of you fathers, if your son asks for a fish, will give him a snake instead? Or if he asks for an egg will give him a scorpion?  If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!”

(John 15:7 AMP) “If you live in Me – abide vitally united to Me – and my words remain in you and continue to live in your hearts, ask whatever you will and it shall be done for you.”

(James 1:17 NKJV)  Every good gift and every perfect gift is from above, and comes down from the Father of lights, with whom there is no variation or shadow of turning.

(2Cor 4:7 NLT) We now have this light shining in our hearts, but we ourselves are like fragile clay jars containing this great treasure.  This makes it clear that our great power is from God, not from ourselves.

(1Cor1:25-31 NIV) For the foolishness of God is wiser than human wisdom, and the weakness of God is stronger than human strength. Brothers and sisters, think of what you were when you were called.  Not many of you were wise by human standards; not many were influential; not many were of noble birth.  But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong.  God chose the lowly things of this world and the despised things  – and the things that are not – to nullify the things that are, so that no one may boast before him.  It is because of him that you are in Christ Jesus, who has become for us wisdom from God – that is, our righteousness, holiness and redemption.
