Contextual Analysis of "against the tide" in Lyrics

swim against

walk against

time to push back

time to push back

you have to find the strength to carry on

to cut the hardest stone

and no one's seeing through it

don't fall asleep

relentless

into the great unknown

i'm sailing on a ship that's bound for light

i leave it all behind to reach for more

i've tried but i just can't seem to fight

so low beneath the foam i can't feel the sun burn my eyes

for challenges to come

under the banner of the brave

lonely diamond

and old horizons

i'd just been gently swimming my way

and she threw out a line to me
