Last Wednesday, our brother Gary passed into the World of Truth, as he finished his journey here on earth and went to make his home with his Lord and Savior Jesus Christ. While we Simon folks lament the loss, we are glad for his sake that he has escaped any further sufferings from the lung disease which beset him and that his soul has now been bound together in the bundle of life. As the apostles said, “We do not grieve as the world grieves” and know that your sympathies are with us along with your condolences, and you have our gratitude for those.
