Tyndale House Publishers had the insight years ago to produce the Operation Worship® military Bible with a waterproof cover and High Heat Glue. These two features are important because, in many areas of battle, temperatures are intense and the glue has a tendency to melt. Our men and women in battle are subject to many differing extremes of weather, including intense rain. Thank you Tyndale House Publishers for taking care of these important details while producing Bibles for Operation Worship®. We are all truly Blessed!
