My former pastor (a Godly man of virtue) taught me to always bring a gift when I visit someone’s house. Not so much an expensive item like a smartphone, just a thoughtful token. It’s the cordial thing to do and shows that you appreciate (and are willing to offset) the host’s hospitality. I’ve embraced that mindset and carry it with me when I do house visitations to sick-and-shut-in church members or to those I do Bible study with.
I have three or four visits scheduled for this Sabbath after church and I’m bringing fresh, baked goods as the gift. I made homemade whole wheat bread and homemade oatmeal raisin cookies, both of them vegan and tasty beyond belief. These items have always been a hit.
