Why would a foolish man try to buy wisdom from another man? If he is a fool and not wise, he will not know whether or not the advice is good anyways. If you are afraid you are not being wise or that you are a fool, there is a remedy: reading Proverbs. The book of Proverbs is filled with wisdom. If you have children, read it to them before they go sleep. Teach others and yourself to value wisdom. It is one thing to not be wise but value wisdom and seek it, if that is the case you will eventually become wise. It is much worse to not care for wisdom or even to choose to stay unwise. The Bible also says that we can pray for wisdom, so go ahead and ask God for some wisdom whenever you need it!
And we pray:
Lord God, You are The God of wisdom and truth. You possess all wisdom and Created it. Lord, make me wise. You have set responsibilities before me, and I want to do them well, so I ask in humility that Your Essence give me wisdom on how to complete the task the best I can. You know me. You know the gifts You have given me. I know that You can never have too much wisdom, so make me wise. And always keep me humble because I do not want to be wise and proud. I come to You in Jesus’ Name. Amen.
