This song seems to be about perseverance in faith, despite feeling like you're unequipped (the first verse) or facing some kind of "attack" (the second verse). By the bridge everything seems hopeless, when God speaks, saying that nothing is unexpected, and that everything will be alright in the end. The chorus seems to be using the setting and rising of the sun as an allegory to its homophone, "son", referencing the death, resurrection, and eventual return of Christ.
