The Spirit searches all things, even the deep things of God. For who among men knows the thoughts of a man except the man’s spirit within him? In the same way no one knows the thoughts of God except the Spirit of God ~ 1 Corinthians 2:10-11 ~

People who do not know God have a hard time understanding God's ways and the Bible because God is Spirit and He speaks to us by Spirit and that is done most often in prayer. It is important to connect with God on a spiritual basis, meaning allowing His Holy Spirit to search our hearts and soul and open our eyes and ears. If you don't spend time in prayer, not just talking, but also listening, how in the world do you expect to hear from and be led by God? If you want to know the thoughts of God, spend time alone in prayer.
