Keep the Faith-Nothing will be impossible for you

This a.m., waiting for the inbound train to work, a fellow bike commuter stopped to say he's thinking of me and to *keep the faith*. I only met Matt last year some time, since we both bike to the train and he lives just a few blocks past me, I introduced myself to him on a ride home last year.

So, as I'm reading the Good Book on the train...it refers to faith loud and clear!

Mark 17: 10-27
10 Then the disciples asked him, "Why do the scribes say that Elijah must come first?"
11 He said in reply, "Elijah will indeed come and restore all things;
12 but I tell you that Elijah has already come, and they did not recognize him but did to him whatever they pleased. So also will the Son of Man suffer at their hands."
13 Then the disciples understood that he was speaking to them of John the Baptist.
14 When they came to the crowd a man approached, knelt down before him,
15 and said, "Lord, have pity on my son, for he is a lunatic and suffers severely; often he falls into fire, and often into water.
16 I brought him to your disciples, but they could not cure him."
17 Jesus said in reply, "O faithless and perverse generation, how long will I be with you? How long will I endure you? Bring him here to me."
18 Jesus rebuked him and the demon came out of him, and from that hour the boy was cured.
19 Then the disciples approached Jesus in private and said, "Why could we not drive it out?"
20 He said to them, "Because of your little faith. Amen, I say to you, if you have faith the size of a mustard seed, you will say to this mountain, 'Move from here to there,' and it will move. Nothing will be impossible for you."
