Hello! I am also new here. Welcome. You have to pray about this, there could be many reasons you are scared, maybe it's nerves or the stress of wedding planning that's getting you all emotional. Talk to the Lord, He already knows how you are feeling, remember when you talk to Him to listen to Him too. Don't be scared, just pray till you no longer are scared, even better both you and your future husband should spend some time in prayer and worship together, sometimes when things get so busy we can't hear God's still voice amidst everything.
