Failure.
Many of the Disciples of Jesus believed that they could follow Him any where. Peter boasted about it, but Jesus warned him that he would deny him three times. Matthew 26:31-35, Mark 14:27-31, Luke 22:31-34, John 13:36-38.
We can all make claims to what we believe in, but when it has to cost us something, fear of man sets in and we all run away. Mark 14:50-51, John 18:15-18, 25-27.
This was just the beginning of a series of events that are part of the Easter Story, all of this was in the will of God.
Ask me and I will tell you!
