The question was posed: “Why are/do some go after their spiritual evolution and others do not?”
Is it that some are predestined or chosen and others are not?
It is a simple matter of choice and free will.
We all have the calling but we choose to listen and follow or we choose not to.
For if we were compelled or driven then it would not be of our free will.
It would be that we are chosen from others.
But this is of no great miracle that one was chosen and received the drive to enter the kingdom of heaven while the one next to them was not but the miracle lies in the fact that when the individual chooses and it is this individual who has shown worth and redeems humanity.
You are the salt of the earth and little salt is needed to season the whole pot.
