Acts 2:14b “…Fellow Jews and all of you who live in Jerusalem, let me explain this to you, listen carefully  to what I say.” Peter knew human nature so he started his explanation—listen carefully.  He is telling you and me—read carefully!  If you really want to learn so you can apply–read and study what I am about to teach you. Peter is also implying —-some of you will not listen and you will therefore miss the entire purpose of Jesus and His life.  You make the choice–listen, learn and apply OR ignore, live with no purpose and gain nothing.  You and I listen carefully to Peter, our inspired writer.
