The first rule to remember is that we live in a fallen world. Take great care before you decide to meet any man or woman for the first time.
Verify the person's photos BEFORE you decide to start talking to them! DON'T ASSUME ANYTHING!
Use TinEye and Bing search. Better to be safe than sorry!
Pray, pray, pray for God's best for you!
Your profile isn't just about you or your personality, it's also about what you expect from the person you want to meet as well as what your personal boundaries are and what attracts you to the man/woman that you are hoping to find. BE PICKY!
Beware of people using photos that don't match their age!
ALWAYS meet in a public place for your first meeting and (for you women) make sure you have a lifeline in place to help you bail if you feel uncomfortable at all during your meeting.
Men and women should tell their friends where they are going and what time they expect to return.
After you feel comfortable with the person you've met is the time to relax.
Be willing to pray for each other when you start talking, while you're apart, and when you meet and when you end your evening. Keep your relationship lifted before God and under His covering!
Remember that breakups may hurt but always learn from your mistakes! Remember that it's the Lord you serve and that He is your fortress and your shield (Psalm 27).
Men, don't be afraid to use your imagination when it comes to romancing her and winning her heart! Candles, soft music, and good food are a great setting, but also remember the little things like complimenting something about her looks, how she's dressed, how she wears her hair, the color of her fingernails, etc. (Also, do the unexpected: take charge and clean up after the meal; if she's had a rough day, offer to wash her feet. Don't shy away from her wanting to return the favor!)
Also, communication about everything is key to a good, solid relationship. Be honest! Be transparent! Let each other know how you feel about each other!
When you include the Lord in all your activities be prepared to be blessed!
Seek the Lord and seek to honor Him in all you do!
Remember, the joy of the Lord is your strength!
