Ephesians 5:17 Therefore do not be foolish, but understand what the Lord’s will is.
Understanding God is difficult because He is just so awesome. I don’t say that in the “He’s really cool” way but in the way that He is just so big and mighty!
Understanding what God wants you to do can be difficult as well if we are not willing to listen; but listening gives instruction and instruction gives direction.
God continue to give us instruction in many ways, through others people, through the bible and even through the world… but we have to listen to Him in the first place.
