The Holy Spirit (Acts 2:38-39) is given to believers in Messiah in this Messianic era to help us live better and lead us and encourage us in life's situations. You can do no better than to follow God’s commandments and how the Holy Spirit is leading you (The Holy Spirit will not contradict God’s commandments – why would God’s good commandments change; God says in Malachi 3:6 NKJV, “For I am the LORD, I do not change.”). Through God’s commandments and the Holy Spirit we can hit the middle of the target in life.
