"Let not your heart be troubled," said Jesus in the Upper Room at the Feast of the Passover, "ye believe in God, believe also in me" (John 14:6, KJV).  When Jesus spoke those words, there were plenty of reasons for His followers to be worried and troubled.  He had just taken a basin and washed the feet of the disciples, telling them that there was a traitor in their midst who would betray Him.  As He took the cup to share the Passover meal, Satan entered into the heart of Judas, who would sell Christ for 30 pieces of silver.
