God has given us His Word so that we can tap into His Wisdom. You see the wisdom of God can be found in His Word. According to scripture in Jer 8:9, the men who rejected the Word of God had no wisdom.
As a child of God, the Word of God must be precious to you. You must create time to dig into the Word of God on a consistent basis. God told Joshua that as he spent time meditating on the Word of God, he will make his way prosperous - Jos 1:8. In other words, Joshua needed to meditate on the Word of God on a continuous basis in order to access and release the wisdom of God needed to succeed in all that he was called to do.
Enough of trying to make it on your own. Man was never designed to live by his own natural wisdom. Rather God makes His wisdom available through His Word so that you and I can live the life we were created for. Friend, be excited that you are not on your own. In every situation the wisdom of God prevails. As you access and apply the wisdom of God in all of your endeavors, you will enjoy tremendous success.
