The first part of Revelation is the last instruction that Jesus ever gave to the churches on earth. What Pastor Bill wants you to take away from these last basic instructions is to follow where God leads you and to show His love to everyone you come into contact with. People should be able to tell you're a Christian just by your behavior and attitude towards others. If nobody knows where you stand spiritually, then you might need to reevaluate how you're reflecting Jesus in your life, and get your heart right with Him.
