Secure and productive places of worship, workplace, private and public events throughout Western Michigan.

God arm us with strength, make our feet like the deer, train our hands for battle, so that our arms can bend the bow of bronze, give us the sheild of victory, your right hand to sustain us, broaden the path beneath our feet so that our ankles do not turn.

– Psalms 18:32-36

Core Values

From that day on, half of the men did the work, while the other half were equipped with spears, sheilds, bows and armor. The officers posted themselves behind all the people of Judah, who were building the wall. Those who carried materials did their work with one hand and held a weapon in the other.

– Neh 4:16-17
