When God asks us to do something for him it can be very overwhelming and cause us to be filled with fear.

I've experienced this myself on a number of occasions when God has directed me to do something for Him.  Singing in front of  people, asking someone how their relationship is with Jesus, or even things as simple as asking someone to come to church can cause me to become afraid.    Nine years ago when He asked me to quit a successful job in Ohio,and move to Kentucky,it was  frightening, but when He told me that I was to open a Christian bookstore in Alexandria, I was terrified.

God has a way of reaffirming and comforting and when we seek Him, He is always there to guide, protect, and encourage us on the journey.   As I struggled with the fear of opening the bookstore He gave me encouragement by validating that He really was asking me to do this. At the time I was struggling with the decision He brought a sermon through our pastor  that if we fail to act on God's calling in our lives that God would find someone else but we'd miss the blessing that He had in store for us.   Another message that spoke very directly to me was the hymn selection on a Sunday  morning when I was about to give up - it was "The Hymn of Promise" which speaks of  how God reveals everything in its season and that from the past comes the future.  My past could very well contribute to the future of His assignment  for me in Alexandria if only I would say  yes.  He continued to confirm and encourage with many other definite signs - stop in sometime and ask me about His provision, I would be honored to share.

In the Bible, Gideon was afraid when God asked him to take just 300 men and attack the forces of the Midianites who were as "thick as locusts" in the valley, and had camels that "could no more be counted than the sand on the seashore".   God knew that Gideon was afraid and gave him a affirmation, and the encouragement needed to fulfill his mission.

Maybe God is asking you  to serve at your local church, perhaps He's moving you to speak with someone about Jesus.  Could even be that you've been asked to serve in a way that is way beyond your means or comprehension.  Whether it's simply to befriend someone, silently serve or to travel to the mission field, God will definitely provide whatever is necessary for you to carry out His will for your life.
