I'm sure you know the old song that says, "All to Jesus I surrender, all to Him I freely give. I will ever love and trust Him, in His daily presence live." That song was written in 1855 by a man with the name of . At that time he was actually in a great battle in his own spirit between; should he develop his gifting in art or should he step out full time for the Lord. A decision that was giving him great turmoil and he was praying about it and struggling with it and then he wrote this song once he came to the place of full surrender.
Did you realise that every prayer you pray is actually a seed in the harvest fields of God? Your prayer can make a difference and bring you rewards you would never have even dreamt of. That's why God invites us so wonderfuly in his Word in Psalm 2:8, "Ask of me and I will give thee the heathen for thine inheritance and the uttermost parts of the earth as thy posession". Now how would that be possible for anybody who isn't travelling; you do it through prayer. That's how you reach the uttermost parts of the earth as thy posession.
