I think first dates deserve as much discernment and prayer as anything else. I used to accept these as I wanted to be open and put my faith in God, but really, the Holy Spirit was already rejecting these "suitors" because He knows the beginning to the end. Some may see it as harmless, but I believe that this opens doors to falsified hope and confusion. Can it be an opportunity to share a conversation about our faith? Sure. However the added layers may be more detrimental than a polite decline.
@Kristina yeah and some men will expect you to go dutch to your surprise and then if they pay and we dont work out, they would say they are used for money. So really discernment and prayers... So many years Im alone and didnt expect to be invited unless with confirmation from God.
