"But a natural man does not accept the things of the Spirit of God; for they are foolishness to him, and he cannot understand them, because they are spiritually appraised." (1 Corinthians 2:14)
"The Bible is a difficult Book because it came from the infinite to the finite - from the unlimited, all-powerful God, to limited man. Therefore you cannot understand the Bible as you would understand the writings of Plato or Socrates. You can study the great philosophers with the natural mind, and by diligent application, grasp their profound meanings. If the Bible could be understood by natural man, it would be a natural book, and could not be the Word of God. Since the Bible is from God, and therefore spiritual, before you can receive its teachings, you must be born of the Spirit (John 3:6) and filled with the Spirit (Ephesians 5:18). Always approach the Bible praying that the Spirit will be your teacher and will guide you to a better understanding of His Holy Word, or it will remain a difficult, closed book (John 16:12-16)."
When you came to believe in Jesus, confessed your sins to Him, asked Him to forgive you, and to become your Saviour and Lord, among many other blessings, you became born again of the Spirit, and received the Holy Spirit to be your teacher and guide. Why not take a moment now to thank and praise Father God for all His many blessings, to thank and praise Jesus for making it possible for you to become a child of God, and to thank and praise the Holy Spirit for working in your life.
May God give you understanding.
