The fear of the LORD is the beginning of wisdom, and the knowledge of the Holy One is insight. Proverbs 9:10
The Bible says a lot about wisdom. The entire book of Proverbs is a book of Godly wisdom. “The fear of the Lord” refers to a reverent knowledge of God; knowing His character and seeking His word in all matters. To fear God means to be aware that worldly wisdom is very often counter to Godly wisdom.
This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666. Revelation 13:18
In the Book of Revelation, John tells us that followers of Jesus will be given the wisdom to be able to discern that all people who take the mark of the beast cannot be saved. God does not leave believers in doubt about such eternally serious matters.
What about important life decisions? We should always go to God in prayer about everything, particularly big decisions. Besides prayer, we should go to the Bible for answers, ask others to pray for our big decisions, and often we should seek guidance from elders or other wise believers in our lives. If you are married, you should pray about these decisions with your believing spouse.
There will be times when the world will offer a pathway that is contrary to the path God wants us to take. It is important to remember that the path that is correct for one believer, may not be the path God has chosen for you.
As in all things, we have to be careful to not allow our biases, or the biases of others to lead us in a direction that God has not intended for us. Seek God first, and you will find every answer.
You will seek me and find me, when you seek me with all your heart. Jeremiah 29:13
