We put God first in our lives by giving Him
(1) the first part of every week.
(2) the first part of every day.
(3) the first dime of every dollar.
That thought seems to give a reason for why we do what we do. It sounds so much better than thinking:
I HAVE to go to keep the Sabbath Day holy.
I HAVE to study scriptures.
I HAVE to pay tithing.
