I feel like I want to grow a longer beard just so I could dread it
You are not serious, get out of here. Why do you want to dread your beard?
I want my beard to look like Jesus Christ
While it's good to look up to someone, it's not good to try to transform yourself into them completely. You are your own individual, and you shouldn't pose as someone else.
But I want to be someone else besides myself.
You have your own personality and looks, be you and only who you are. Proud is what you should be of your own individual features and characteristics.
