Doubt, nervousness, fear, etc. These were the emotions overcoming Gideon as he worked toward submitting to the Lord’s will for his life. 
Within a short period of time those feelings were changed to boldness, confidence and reassurance. 
Gideon hit the ground running when he undoubtedly received confirmation that he was in the Lord’s will. He found men to share his plan for moving forward. He left no time to back peddle. 
Maybe you feel like you’re being called to step out of your comfort zone. Right now you may be only experiencing uncertainty. If the Lord makes it clear to you that yes, he is speaking–step out boldly! Find someone that will support you and share the good news and pray about what to do next.
