These are some of the scriptures I've learned about how important a personal relationship with Jesus is and why we shouldn't be dependent upon an organization but the holy spirit.
john 16: 12-15 -"I have much more to say to you, more than you can now bear. 13 But when he, the Spirit of truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. 14 He will bring glory to me by taking from what is mine and making it known to you. 15 All that belongs to the Father is mine. That is why I said the Spirit will take from what is mine and make it known to you.
1 John 2:27 -As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him.
John 3:16-21: 16 "For God so loved the world that he gave his one and only Son, [f] that whoever believes in him shall not perish but have eternal life. 17 For God did not send his Son into the world to condemn the world, but to save the world through him. 18 Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son. [g] 19 This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. 20 Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. 21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God."

John 3: 31-36: 31 "The one who comes from above is above all; the one who is from the earth belongs to the earth, and speaks as one from the earth. The one who comes from heaven is above all. 32 He testifies to what he has seen and heard, but no one accepts his testimony. 33 The man who has accepted it has certified that God is truthful. 34 For the one whom God has sent speaks the words of God, for God [k] gives the Spirit without limit. 35 The Father loves the Son and has placed everything in his hands. 36 Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God's wrath remains on him."

Matthew 18:20 -"For where two or three come together in my name, there am I with them."
1 Cor. 11:3 - Now I want you to realize that the head of every man is Christ, and the head of the woman is man, and the head of Christ is God.
