In the study of Proverbs we must keep in mind that these proverbs are not promises. They are rather a collection of sayings which do happen in the general sense of things.
“Hear, ye children, the instruction of a father, and attend to know understanding. For I give you good doctrine, forsake ye not my law. For I was my father’s son, tender and only beloved in the sight of my mother. He taught me also, and said unto me, Let thine heart retain my words: keep my commandments, and live. Get wisdom, get understanding: forget it not; neither decline from the words of my mouth. Forsake her not, and she shall preserve thee: love her, and she shall keep thee. Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding. Exalt her, and she shall promote thee: she shall bring thee to honour, when thou dost embrace her. She shall give to thine head an ornament of grace: a crown of glory shall she deliver to thee. Hear, O my son, and receive my sayings; and the years of thy life shall be many. I have taught thee in the way of wisdom; I have led thee in right paths. When thou goest, thy steps shall not be straitened; and when thou runnest, thou shalt not stumble. Take fast hold of instruction; let her not go: keep her; for she is thy life.” Proverbs 4:1-13 (KJV)
Hold on to wisdom; like a family heirloom. Children are the fruit of marriage, and the responsibility of their teaching, their learning is that of the father and mother. It is, however the responsibility of the child to learn the teachings which they are taught. Hearing instruction; godly instruction; as lived by the parent is necessary for the child to see as well as hear.
Cramming Scripture into the child’s life; especially for correction; will make the child hate it rather than love Scripture and God. When they see their mother and father reading and studying Scripture, praying, and living their lives like they teach them then it will have an affect on the child’s life as well.
When God is our Father, our Instructor/Teacher we know that His teaching is never in error. If we err from His teaching it is the child who errs not the Father. Remember Wisdom is personified in Proverbs, and is seen in the New Testament as Jesus Christ, Son of the Living God; God the Living Son.
