Be honest
Be upfront about your Christian views: after all, this is a shared belief that has brought you together. Being open about what you believe helps you both see early on whether you are well matched. Be honest about who you are as well. It's an old rule, but don't stretch the truth about who you are and what you do, as it might come back to haunt you. As Proverbs 20:17 puts it, "Bread gained by deceit is sweet to a man, but afterward his mouth will be full of gravel" (ESV).
Don't come on too strong
As a Christian, marriage may well be at the front of your mind when you look for a partner. Even so, leave the marriage talk off the first date. It's a huge commitment, and while it may be on the horizon if the two of you are happy together, it can be off-putting to talk about something so serious so soon. Use the first date to find out more about each other. Be careful, too, about physical contact without asking first. You might feel comfortable holding hands or giving a kiss on the cheek when you say goodbye, but your date might not until you know each other better.
Seek advice
Turn to the Bible, your vicar, your priest or a trusted friend for a few words of advice or encouragement. Lots of people you know will have had first date nerves, so ask what got them through. And bring the evening to God before you go: "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God" (Philippians 4:6, NIV).
