I'd say it's a non-religious song that could easily have religious applications. The imagery is similar to that found in many religious songs, without being overtly religious. It's certainly a thought-provoking song.

The song has been posted in the forum with chords, but it's a little easier to follow without the chords. So...I'll post it.

READY FOR THE STORM
(Dougie MacLean)

Oh, the waves crash in and the tide pulls out.
It's an angry sea but there is no doubt
That the lighthouse will keep shining out
To warn the lonely sailor.

And the lightning strikes and the wind cuts cold
Through the sailor's bones to the sailor's soul
Till there's nothing left that he can hold
Except the rolling ocean.

CHORUS
But I am ready for the storm, yes, sir, ready.
I am ready for the storm, ready for the storm.

Give me mercy for my dreams, for every confrontation seems
To tell me what it means to be this lonely sailor,
But when the sky begins to clear, and the sun it melts away my fear,
I'll cry a silent weary tear for those that need to love me.

But distance it no is no real friend, and time it takes its time,
But you will find that in the end it brings you me, the lonely sailor,
But when you take me by your side you love me warm, you love me,
And I should have realized I had no reasons to be frightened.
