Expect the Lord's work to bring opposition-in fact, we are told it will so it shouldn't be a surprise when it does.  What to do when it does?  Pray and press onward.  Sometimes the opposition will be verbal.  But sometimes it might be physical.  When enemies of the Lord cast seeds of doubt, take them captive and filter them through the Scriptures and through prayer.  Then, reply on the power of God to fuel the work He has called you to do.  Draw strength and confidence from His word.
