How do you live in this world - filled with wars and chaos - with no hope of redemption or things getting better, and just thing “yep, this is all there is, life is good”. As Christians, we have assurance, certainty and comfort in that Jesus is coming back to judge the world, destroy all the wicked and bring us to eternal life. Atheists don’t have that. Even worse, some even prefer to insult this God. What’s keeping me grounded in this life is the knowledge that God dictates when my life ends- not me.
So?
Is the love you have for your significant other worthless then? Is going abroad to experience new things worthless?
In the long term, yes.
I don’t share this position at all. Life is all about experiencing things, things that you can repeat, things that are once-in-a-lifetime and things that will stay with you.
