The Sixth letter John was asked to write was to The Church at Philadelphia – the letter that was filled with applause and encouragement. Jesus wanted to remind this church that He is always in control. Philadelphia was located on a fault line and this little city was devastated by earthquakes and tremors but in the process this little church existed to help those in need. Jesus reminds them that for all the bad – they are not forgotten.
