You could pick a side in one of the endless wars but the man or woman of faith has his equipment and marching orders for the war of all wars - from which all the lesser battles are spin-offs.
For a Christian, you may have the Treasure of all worlds inside you. The wisdom and light of the Ancient of Days. The excellency of the power that comes from God, and is unattainable by men. Yes, you may have all the best ideas, but unless you strap on your armor and engage (in the power of resurrection) your ideas have little impact. Living to ourselves we actually withhold the opportunity for full life, freedom and truth from those whom we criticize for fighting the wrong fight.
We were so redeemed to rescue - by grace subdued, that we might conquer. There are no conscientious objectors to the mission of the Gospel - sitting out is not an option. There are demonic works to destroy, there are lost to find, there are bound to release. So, who's to do it?
