We, as humans, rely on the elements of the Earth, which are water, wind, earth, and fire. As Christians, sometimes we want to fight back with the physical elements of the Earth, but the scripture in the Bible teaches us that this is not a battle of flesh and blood, but of the spirit. We should rely on the spiritual things that God has placed before us, such as prayer, scripture, and fasting. Jesus, while being tempted, did not fight with earthly things; instead, He fought spiritually.
