I'm not 100% sure about this translation. Especially the 'this concept (=nanda tte koto)' part.
translation
That miracle that we, who turned our tears into just one prayer, saw
On that day in that instant is no illusion
However I wonder if it’s sad to be swept away by the ordinary
*When you’re in despair, try to remember
“This day called today on which you’ve decided to give up,
Is the tomorrow on which somewhere, someone didn’t want to give up.”
**And remember that I am tightly, tightly
Holding this concept and your hands
Thus I want to firmly face another sunrise
Please don’t be afraid of wanting to take a step forward
***When you slam into a wall, try to remember
“This day called today on which you seem to be losing
Is the tomorrow on which somewhere, someone wanted to fight.”
****And remember, no matter how far away
Your hands are connected to this concept
*repeat
**repeat
***repeat
****repeat
