On Sunday morning, as families gathered throughout the United States to celebrate Father’s Day, the pastor of the Assembly of God Church in Oakville, Washington delivered a sermon tailored specifically for the holiday.

As Pastor David George brought that sermon to a close, he used the holiday as an opportunity to call on the men of his church to play an active role in the world around them:

God, don’t let us be content as men to just let life go by. Let’s not be content, Lord, to just see the world around us burn. Instead, help us to get involved. Help us to do something that’s going to produce Godly effort and Godly results in people’s lives.”

As the families in his congregation filed out of their seats and to their respective homes, George and his family, including his wife, daughter, and granddaughter, also set about their day — making the nearly 30 mile drive to Walmart in nearby Tumwater. All in all, it was a pretty average Sunday for the community leader: a well received sermon, a day shopping with the family but then, as George and his entourage of family members waited in the checkout line, thunderous bangs rang out from the back of the store.
