Moroni cannot imagine what might cause these judges to withhold the rightful support of the armies in the field. He suggests that perhaps they have decided that God will protect them. While Moroni is himself a man of great faith, he understands that God still requires the active participation of his people. God may assist us, strengthen us, and preserve us at times, but he does expect that we shall also act in our best interests. When the Lamanites fell on the people of Ammon (then called the Anti-Nephi-Lehies) many were killed. They were humbly fulfilling a sacred oath with tremendous faith, yet many were killed. God works with us, not instead of us.
