Here be my opinion on the questions...
Do we jump into the dark where we are not known?
The dark will eventually jump onto you, anyway, so better do it on your terms.
Or do we prefer to stay where we are comfortable. Which is better?
We do. But that's a bad habit. Growth is where you challenge yourself and go out of that comfort zone. Well, enjoy it when you need some rest and recharge, but then continue forward before getting...too comfortable.
There is good and bad in the unknown, the risk is always there, but are we willing to risk it?
As hinted in my first answer, there is also risk in waiting for the unknown to happen to us. Risk is always there. Acting brings risk. Not acting brings risks. Learn to compare and evaluate those.
Do we believe in the good and do we truly believe that everything is beautiful?
Believe that it's good to be good but the bad and the ugly do exist. They shall always be there for us to deal with. Or don't deal with. Up to us.
Is faith important? Does it help us?
Have faith in yourself and the potential for good you meet, but also...remember not to get too comfortable. Be ready to challenge your faith and update it. You must constantly prove to yourself you are worthy of it. Accept the failures. And keep going.
Thanks for chiming in always. What you say is extremely wise and each of us can take the positive from what you say. Thank you <3
