Have faith in God.

Mark 11:22 Jesus says; Have faith in God.
Jesus spoke to the fig tree the day before and today it is withered away.
I have heard simply years of preaching on verses 23 & 24.
Without fail I have been taught that following this guide-line, described in these verses, is how I get my prayers answered.
According to the context of this passage I would say that Jesus, in verses 23 and 24, is indeed describing his statement, Have faith in God.
Jesus life is an example of faith in God and not only was what happened to the fig tree one proof of his faith in God, but his entire life is an example of his faith in God. Here are some of the things that are absent from Jesus' requests in his prayers.
1. Selfish motives to promote himself were absent
2. Selfish motives to gain materially were absent
3. Selfish motives to manipulate others was absent
4. Selfish motives of vindication were absent
5. The quoting of the scriptures and calling them prayers was absent.
Have faith in God.
