Have you been "born again"?  If you have, you belong to Christ; but without the new birth you cannot be His.  In whom do you trust?  For those who believe in Jesus are the sons of God.  Whose work are you doing?  You are sure to serve your master, for he whom you serve is thereby owned to be your lord.  What company do you keep?  If you belong to Jesus, you will fraternize with those who wear the livery of the cross.  "Birds of a feather flock together."  What is your conversation?  Is it heavenly, or is it earthly?  What have you learned of your master? - for servants learn much from their masters to whom they are apprenticed.  If you have served your time with Jesus, it will be said of you, as it was of Peter and John, "They took knowledge of them that they had been with Jesus."
