Do we even really need God?

Sometimes I ask myself:
What is the purpose of life?
Why are we here?
So I get a college education, get a job, work, then die.
So what's the point?
I won a national championship, in three years nobody will remember who I was.
Why do we work so hard?
I couldn't even tell you my great grandfather's name.
Pretty good chances that my great grand kids won't know mine.
So why do we toil?
Why do we work so hard?
Why do we care?
Because this isn't it.
There is more to life.
There is hope for something after this.
Our lives are lived in a way that we can be independent and rely on ourselves, but when we lay in bed at night, there are always things that haunt us.
Purpose is something that always crosses my mind.
If any man builds on this foundation using gold, silver, costly stones, wood, hay or straw, his work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each man's work. If what he has built survives, he will receive his reward. If it is burned up, he will suffer loss; he himself will be saved, but only as one escaping through the flames.
I don't want to narrowly escape through the flames.
God is our purpose.
Our hope is in him.
Without God, life is nothing.
Even if we impact someone's life, we will both die and that relationship will be meaningless.
God promises more.
God guarantees full life not only in this life, but in the next one.
Resurrection.
Purpose.
Meaning.
Hope.
