Jeremiah 4:22 For my people is foolish, they have not known me; they are sottish children, and they have none understanding: they are wise to do evil, but to do good they have no knowledge.
Eighteen the age when the world considers you an adult old enough to be on your own, if you had left three years earlier when you knew everything you wouldn’t have any problems at all. Welcome to the onset of Alzheimer’s. 
(Matthew 18:1 – 14) At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven? And Jesus called a little child unto him, and set him in the midst of them, And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven.
Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.
And whoso shall receive one such little child in my name receiveth me. But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea.
Woe unto the world because of offences! for it must needs be that offences come; but woe to that man by whom the offence cometh! Wherefore if thy hand or thy foot offend thee, cut them off, and cast them from thee: it is better for thee to enter into life halt or maimed, rather than having two hands or two feet to be cast into everlasting fire.
And if thine eye offend thee, pluck it out, and cast it from thee: it is better for thee to enter into life with one eye, rather than having two eyes to be cast into hell fire. Take heed that ye despise not one of these little ones; for I say unto you, That in heaven their angels do always behold the face of my Father which is in heaven.
For the Son of man is come to save that which was lost. How think ye? if a man have an hundred sheep, and one of them be gone astray, doth he not leave the ninety and nine, and goeth into the mountains, and seeketh that which is gone astray? And if so be that he find it, verily I say unto you, he rejoiceth more of that sheep, than of the ninety and nine which went not astray.
(Matthew 18:14) Even so it is not the will of your Father which is in heaven, that one of these little ones should perish.
(Luke 18:15 – 20)
And they brought unto him also infants, that he would touch them: but when his disciples saw it, they rebuked them.
But Jesus called them unto him, and said, Suffer little children to come unto me, and forbid them not: for of such is the kingdom of G-d. Verily I say unto you, Whosoever shall not receive the kingdom of G-d as a little child shall in no wise enter therein. And a certain ruler asked him, saying, Good Master, what shall I do to inherit eternal life?
And Jesus said unto him, Why callest thou me good? none is good, save one, that is, G-d. Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother.
Psalms 18:1-50 I will love thee, O LORD, my strength. (2) The LORD is my rock, and my fortress, and my deliverer; my G-d, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower. (3) I will call upon the LORD, who is worthy to be praised: so shall I be saved from mine enemies. (4) The sorrows of death compassed me, and the floods of ungodly men made me afraid. (5) The sorrows of hell compassed me about: the snares of death prevented me. (6) In my distress I called upon the LORD, and cried unto my G-d: he heard my voice out of his temple, and my cry came before him, even into his ears. (7) Then the earth shook and trembled; the foundations also of the hills moved and were shaken, because he was wroth. (8) There went up a smoke out of his nostrils, and fire out of his mouth devoured: coals were kindled by it. (9) He bowed the heavens also, and came down: and darkness was under his feet. (10) And he rode upon a cherub, and did fly: yea, he did fly upon the wings of the wind. (11) He made darkness his secret place; his pavilion round about him were dark waters and thick clouds of the skies. (12) At the brightness that was before him his thick clouds passed, hail stones and coals of fire. (13) The LORD also thundered in the heavens, and the Highest gave his voice; hail stones and coals of fire. (14) Yea, he sent out his arrows, and scattered them; and he shot out lightnings, and discomfited them. (15) Then the channels of waters were seen, and the foundations of the world were discovered at thy rebuke, O LORD, at the blast of the breath of thy nostrils. (16) He sent from above, he took me, he drew me out of many waters. (17) He delivered me from my strong enemy, and from them which hated me: for they were too strong for me. (18) They prevented me in the day of my calamity: but the LORD was my stay. (19) He brought me forth also into a large place; he delivered me, because he delighted in me. (20) The LORD rewarded me according to my righteousness; according to the cleanness of my hands hath he recompensed me. (21) For I have kept the ways of the LORD, and have not wickedly departed from my G-d. (22) For all his judgments were before me, and I did not put away his statutes from me. (23) I was also upright before him, and I kept myself from mine iniquity. (24) Therefore hath the LORD recompensed me according to my righteousness, according to the cleanness of my hands in his eyesight. (25) With the merciful thou wilt shew thyself merciful; with an upright man thou wilt shew thyself upright; (26) With the pure thou wilt shew thyself pure; and with the froward thou wilt shew thyself froward. (27) For thou wilt save the afflicted people; but wilt bring down high looks. (28) For thou wilt light my candle: the LORD my G-d will enlighten my darkness. (29) For by thee I have run through a troop; and by my G-d have I leaped over a wall. (30) As for G-d, his way is perfect: the word of the LORD is tried: he is a buckler to all those that trust in him. (31) For who is G-d save the LORD? or who is a rock save our G-d? (32) It is G-d that girdeth me with strength, and maketh my way perfect. (33) He maketh my feet like hinds’ feet, and setteth me upon my high places. (34) He teacheth my hands to war, so that a bow of steel is broken by mine arms. (35) Thou hast also given me the shield of thy salvation: and thy right hand hath holden me up, and thy gentleness hath made me great. (36) Thou hast enlarged my steps under me, that my feet did not slip. (37) I have pursued mine enemies, and overtaken them: neither did I turn again till they were consumed. (38) I have wounded them that they were not able to rise: they are fallen under my feet. (39) For thou hast girded me with strength unto the battle: thou hast subdued under me those that rose up against me. (40) Thou hast also given me the necks of mine enemies; that I might destroy them that hate me. (41) They cried, but there was none to save them: even unto the LORD, but he answered them not. (42) Then did I beat them small as the dust before the wind: I did cast them out as the dirt in the streets. (43) Thou hast delivered me from the strivings of the people; and thou hast made me the head of the heathen: a people whom I have not known shall serve me. (44) As soon as they hear of me, they shall obey me: the strangers shall submit themselves unto me. (45) The strangers shall fade away, and be afraid out of their close places. (46) The LORD liveth; and blessed be my rock; and let the G-d of my salvation be exalted. (47) It is G-d that avengeth me, and subdueth the people under me. (48) He delivereth me from mine enemies: yea, thou liftest me up above those that rise up against me: thou hast delivered me from the violent man. (49) Therefore will I give thanks unto thee, O LORD, among the heathen, and sing praises unto thy name. (50) Great deliverance giveth he to his king; and sheweth mercy to his anointed, to David, and to his seed for evermore.
