When we have that new life in Christ, we have a predator too. Just like the butterfly needs to be aware of his surroundings and how its predators can attack him, so do we as Christians. The devil is out there and he is seeking us out. He's our "adversary".
Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour. 1 Peter 5:8
I used to wonder why I'd see butterflies sometimes sitting on a branch, just sitting there, almost not moving for a very long time, with maybe just a slight movement of the wings. Apparently they were soaking up the sun in order to take flight.
Wow! That is how we are as Christians. We can't do things on our own. We need the "Son" to warm us as well. We don't move along very well in our own strength, do we? We have to rely on the Lord's strength and guidance before we can accomplish anything.
I can do all things through Christ which strengtheneth me. Philippians 4:13
As Christians we have a special eyesight as well and we can see things others don't. Sometimes those without Christ just don't understand us Christians. We have the ability to see with the eyes of faith.
I think of all of those heroes of faith in Hebrews chapter 11 and all the things that happened because of their faith.
Now faith is the substance of things hoped for, the evidence of things not seen. Hebrews 11:1
