Sam inspires Frodo to not give up, no matter how dark the story gets.
“They kept going, because they were holding on to something!”
What Sam describes as ‘some good in this world’, I believe, points to God.
If there is no God, no standard of good or evil, then there is such thing as good or bad.
What is is; who’s to say that one thing is evil and one thing is good.
But we all intuitively sense that there ‘something good’ and it’s worth fighting for.
That’s because God created us to know – and to long for – good.
And yes, God is working towards a happy ending, no matter how dark this world gets.
Don’t give up, keep hanging on, keep pressing on, God and good will triumph one day!
A new day will come!!!
