I believe what ever you do will come back to you.
What you sow is what you will reap.
If some one steals and kills and such right now and it appears they are getting away with it however when it comes back to them (and it will) they will be stolen from and even cause their own death because of the stealing and killing they are doing.
On the other hand when you do good to others and help and bless others and inspire others, it may not appear that all your good deeds and words and such are doing nothing but rest assured, it will come back. Your faith determines how much you will get back.
But honest the law of sowing and reaping is a law no one can separate from, it's a law that always applies in life, period. GOD IS GOOD :)
