Jesus and Prayer

I've been studying the book of Matthew and I've really been struck by how much Jesus taught about prayer.
Andrew Murray made this observation:

"In all His instructions, our Lord Jesus spake much oftener to His disciples about their praying than their preaching.  In the farewell discourse, He said little about preaching, but much about the Holy Spirit, and their asking whatsoever they would in His Name."

Several times I read how Jesus went off and prayed by himself.  If Jesus had to take time alone to pray, how much more do I need to?  I'm thinkin' alot. 

If you believe, you will receive whatever you ask for in prayer.  Matthew 21:22
