If you need to see and know the Messiah before you will believe that he has returned, you are probably one of those individuals who needs proof that light exists, before you will take the chance at flipping the light switch. The problem is that you will never experience the light if you refuse to flip the switch, and turn it on.
Practicing righteousness is the only genuine methodology by which you can know God. When you do what he says you should do, your spirit is awakened. It is alive. It is renewed. It is faithful. It is joyful.
The Lord God Almighty El Shaddai
