Do Rainbows Have Ends?

Just do the best you can you've got to try
You do not need a plan but you may die
If you don't understand the reason why
Usually this plane and say goodbye
I guess through the things you've got to give
Give it all you've got
It's the only way to live

After all you've done he surely will forgive
And your life will break before you end this song
And the tears you spill end raw
It's all I have to give you on my own
I've done my very best but it's a start
And love is all I really have to give
Am giving it all I have
The only way to live
After all I've done
And maybe all I've done he surely will forgive
And when I see him I will love to play this song
If I do not play it wrong
