Many adults are ego driven, pride filled, and many teach "do as I say not as I do". All of us are the product of our education, society, experiences, and what we have been taught.
I have studied the early history of Christianity including the development of the canon. Some of what you have shared is true, but not all of it.
Matt 7:7-12
7 "Ask, and it shall be given to you; seek, and you shall find; knock, and it shall be opened to you. 8 "For everyone who asks receives, and he who seeks finds, and to him who knocks it shall be opened. 9 "Or what man is there among you, when his son shall ask him for a loaf, will give him a stone? 10 "Or if he shall ask for a fish, he will not give him a snake, will he? 11 "If you then, being evil, know how to give good gifts to your children, how much more shall your Father who is in heaven give what is good to those who ask Him! 12 "Therefore, however you want people to treat you, so treat them, for this is the Law and the Prophets. NAS
The meaning of the Greek is ask and keep on asking; seek and keep on seeking; knock and keep on knocking for those who are persistant in asking, seeking, and knocking will result in receiving and finding and having the door opened to them.
