On That Night

On the night He was betrayed, Jesus ate with His Disciples.
On the night He was betrayed, He washed their feet.
He talked to them.
He scared them.
After giving them the cup and the loaf, he spoke some more to them.
John says that he told them very specifically the reason why they had no reason for fear:

John 16:33 I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world.

He didn't tell them He was going away to cause them fear, He told them because He went to prepare a place for them. He didn't tell them that they would scatter at His arrest because He wanted to shame them. He wanted them to understand, Jesus came to do God's will, and God's will would be done. In the world we certainly have trouble.
Sin traps us.
We forget who we are.
People let us down.
We walk through the world, and sometimes it seems we are unforgivable because of what we've seen or done.
Sometimes it seems like the world wins every time evil wins. 
Take heart. Jesus overcomes this world, and through this gathering together to partake of the meal He gave us, we remind ourselves that Jesus always overcomes the world.
