The answer
Your spiritual love must be given to all people, and not be isolated to just Christians. There is a big difference between friends and acquaintances. Your friends should be Christian, to help you build your spiritual life, but you can have many acquaintances in society - at school, at university, at work, and so on. When I say “socialise with them”, I mean be on good terms with them, have pure Christian love for them, caring and sharing with them. If they are sick you must visit them, if a family member or friend has passed away, you must go and give your condolences, if they are celebrating a feast, such as Ramadan, you must give them your best wishes. Therefore you must have pure Christian love towards them, but do not have an intimate relationship with them because they differ in their thoughts, their principles, their ideas, their philosophies and their practices. Have friends from within the church, and have as many acquaintances as you like in society. Express your Christian love to them; go with them when it is right, and withdraw from them when they do wrong.
