I am not sure if the drowning in the high sea is literal or metaphoric. I get the metaphor better than the literal.
The song equates our life with our footprints. We must be happy with our footprint.
Let our footprint do good. Yes.
We have snow here. If I leave you footprints in the snow, I want them to be wise.
And after my meditations, which are not meant to be mean, have been considered, set my thoughts to the edge of the table, and do what's right. I expect my leader to make good decisions.
