We begin a new study today in 1 John. It’s a book that has been a great source of comfort and strength for millions of Christians over the centuries. In fact, John tells us himself that the main reason he wrote the book is that our joy might be full. And God doesn’t just want us to have cups that are full, He wants us to have so much joy that it overflows to others. John will show us how to have cups that are overflowing in this very encouraging New Testament book.
