Whenever something is billed as "free," it might be free to the recipients, but we can be sure that somebody paid for it. People go to soup kitchens for a free lunch, but someone supplies the food, the building, the work of preparation, etc. There is a cost involved. God invites people to come and receive the "free gift" of life eternal. This gift is free to those who will accept it, but there was a great cost to God to provide this gift. Just what did this cost the Lord?
