God's armor includes the shoes ... in which we are commissioned to go out and proclaim the Good News of the Gospel of salvation through the atoning death of Jesus Christ on the cross.

"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
For God sent not his Son into the world to condemn the world; but that the world through him might be saved" Jn3:16,17
