Praying does not mean convincing God to do your will, but His will through you. God needs a willing vessel to yield unto Him, to do His work of preaching the Good News about Him. The question rings, how do you know your purpose? Look at what you are currently doing at work and ask God how you can use your gift in the Kingdom of God. God will show you exactly were you fit.
