You (man) be a believer or a disbeliever

I (God) don’t care

I (Law of nature) make you rich and poor, happy and sad, sick and healthy, blind and visible, deaf and dumb, able and disable

Is all to REALIZE me (God)

If you fail to REALIZE ME (God)

You will be caught in my Karma cycle which you created 

However 

If you fail to REALIZE ME on earth, you will never REALIZE me
(God) in the hereafter

Man, who is blind on earth shall be blind in the hereafter 
Quran 17.72
