This is the victory that conquers the world: our faith. Who is the one who conquers the world? Surely the one who believes that Jesus is God’s son! (5:4b-5)
If faith is believing in what you cannot see, then a person without faith is limited only to what they can sense in some way. A no-faith life is really a life of the here and now. How can there be hope for something else, something better, some amazing renewal? Imagine if this is all there is to life? There are many great blessings to this life right now, but there are just as many set-back and heartbreaks.
Faith is what moves us beyond the worldly limitations, disappointments and darkness. Faith is what allows us to believe that there once was a better world and there will once again be something better. Faith allows us to rise above the boundaries of our own present realities.
And, of course, it is all possible because of Jesus.
