ClemofNazareth said of the song:

Reasons for waiting is a bit of a jam song, just a little bit of pretty much every instrument on the album finds its way into this one. Here again the bass is surprising prominent for a folk album.

The Whistler says:

Reasons for Waiting is another lush ballad, and it sounds suspiciously like “Look into the Sun,” with the lyrics softer, and the musical emphasis being transferred to flute and a string quartet (David Palmer is already an unofficial member). Oh well, it’s a great tune Ian ripped himself off with, and it’s still gorgeous.

Chicapah says about the song:

Next is the beautiful “Reasons for Waiting,” an extraordinary ballad that features organ, harmony flute lines and a lush orchestral score behind Ian’s honest vocal. “Came a thousand miles/just to catch you while you’re smiling” he sings. Melts your heart, don’t it?

And finally, Tarkus1980 says:

“Look Into the Sun” and “Reasons For Waiting” do sound a bunch alike, but they’re still simply gorgeous, and they’re easily the best slow ballads that Ian would ever write (though a small number come close). The latter is also the first instance of David Palmer’s association with the band, as he arranged strings for it in a wonderful way. Keywords for these are: rich vocals, crisp tender vocal melodies, logical chord progressions, gorgeous fluting.

What a sight for my eyes
To see you in sleep.
Could it stop the sun rise
Hearing you weep?
You’re not seen, you’re not heard
But I stand by my word.
Came a thousand miles
Just to catch you while you’re smiling.

What a day for laughter
And walking at night.
Me following after, your hand holding tight.
And the memory stays clear with the song that you hear.
If I can but make
The words awake the feeling.

What a reason for waiting
And dreaming of dreams.
So here’s hoping you’ve faith in impossible schemes,
That are born in the sigh of the wind blowing by
While the dimming light brings the end to a night of loving.
