This is a cactus wren, the state bird in Arizona. This bird knows how to exist in the desert. It doesn’t need any freestanding water to survive, being able to get all the moisture it needs from its food. It also has learned to take good advantage of the prickly nature of cactus.
Perhaps the most menacing of the cacti is the jumping cholla, a plant that will have sections break off and lodge itself in unwary passersby. These sections then will work their way deeper into the victim as they attempt to get free, unless they know exactly how to remove them. Cactus wren will commonly nest in these plants though, skillfully building down in the middle of the cacti’s natural defenses.
This does not stop all possible predators, but attempting to raid a nest is unlikely to succeed because not only is the location highly defensible, but the birds are known to aggressively defend their homes. When a predator attempts to access it, the birds will knock them off balance amid the deadly spines.
One story of such an event is on the Cornell Lab of Ornithology website. They mention a Yuma antelope squirrel that was knocked into the spines and then to the ground. The cactus wren is able to successfully defend its nest because of the combination of a defensible position and aggressive defensive behavior.
Believers should take note of this combination.
The first step to success is to find a defensible position. The easiest way for a Christian to remain in a defensible position is to carefully and closely align yourself with God. Being in agreement with Biblical morality and strong in your personal relationship with God through Christ will allow you to miss the attacks that come from being unprepared and practicing immorality. Much of the warfare believers face is because they are living morally compromised and spiritually distant.
The second step is to know when and how to fight back for the remaining attacks. This can be tricky because our warfare is not like the battles of this world, so our defensive behavior needs to be different. Very often it is a Spirit led word of witness for the Lord. There may be times when the appropriate defense is to simply to explain a misunderstanding, socially or theologically. Increasingly in our world, the defensive component includes political involvement such as voting, campaigning, and political action campaigns. In all cases, our defense includes speaking out, not rudely, but gently and truthfully.
Consider Ephesians 6:11-13 (HCSB)
Put on the full armor of God so that you can stand against the tactics of the Devil. For our battle is not against flesh and blood, but against the rulers, against the authorities, against the world powers of this darkness, against the spiritual forces of evil in the heavens. This is why you must take up the full armor of God, so that you may be able to resist in the evil day, and having prepared everything, to take your stand.
