I don't know if this is what you want but in Matthew 14: 22-36 Jesus talks of Peter needing to step out of his boat and use his faith. Also Moses was scared to be a leader because he spoke with faltering lips....God wanted him to step out and set the people free. This is in Exodus 6. Sorry if this isn't what you were thinking of.
I don't think there's a verse specifically telling you to do this, but the story about Peter walking out on the water to meet Jesus is about this. There are other stories as well, such as the Samaritan who helped the injured man at the side of the road, the Parable of the Talents, Martha being admonished to stop being so busy, probably others I can't think of right now.
2 Timothy 1:7 "God has not given us the spirit of fear..." may indirectly apply to what you are looking for. I think one translation may say "timidity" instead of "fear" ;) Ah, I see someone has already beat me to it! lol
Genesis 12: 1-3 God call Abraham to leave His Country. ( to leave his comfort zone) Comfort zone mean where he feels secure comfortable with no worries, and doing the ordinary with no change. God calls all Christians to get out of your comfort zone, in your spiritual Life, Example, Go travel and visit a family member or friend who has not accepted Jesus., Witness to the person. watch less tv and read more of the Bible. Instead of shopping on friday's go to a Bible Study Class ect... ( Get involved more with the church activities) ect.... Plan better changes in your life for Gods purpose ect......

Faith comes by hearing...Romans 10:17. Stay in the Word and eventually God will move you and you will be out and in His zone and with comfort. Jesus said my food is to do what the Father told him. He was always out of his comfort zone yet in. It's the way of life. To me... as a believer there is no such thing as a "comfort zone". We are always moving even when were not because of Him. ...It's no longer I that lives... He who began a good work in you will be faithful to complete it.
