Salvation starts a person on the road to heaven.
After salvation, sanctification, the process of
becoming holy or set apart for God's use, should
consume our remaining physical life-time.  When I
think of my past, perhaps one of the biggest earliest
milestones I remember was my desire to raise my sons
under God.  Since my own earthly father had died
years before I had had a bumpy road recognizing and
accepting my heavenly Father in every way as simply
"my father".  I can recall that prayer over 25 years
ago when I asked my heavenly Father for help; for
instructions in child rearing.  I reminded Him of his
promise "I will be a father to the fatherless".
In my sprit He answered: the instructions are in the
Bible.  He also instructed me that my sons would see
and develop an understanding of Him in proportion to
my own heavenly Father/son example. This task had not
just become a righteous responsibility but had become
my calling for the next 20 years or so. Was I a perfect
father?  no.  For example, I knew that when my action
was motivated by evil I needed to quickly confess and
ask for forgiveness, and yes even from my own sons.
I wanted to become "mature ... [one of those] who have
their powers of discernment trained by constant practice
to distinguish good from evil" [Hebrews 5:14].

Why Vote?
About 15 years ago I prayed regularly and enjoyed reading the
Bible. I thought I was a good husband and father. I was
satisfied with my sanctification process but God was about to
replace my comfort with some thorns. Suddenly, I found that the
public schools began sex education for my 5th grade son.
I had learned from the Bible that education was my responsibility
and the kind of sex education the government would teach my
son would at worst be contradictory to my own teaching and at
best be sterilized of any biblical truths. When I asked why this
was happening I got the usual runaround: "My hands are tied,
in order to get [state/federal] money some bureaucrat you can't
get to talk to right now decided this had to be done." The
answer was a political one and it bothered me.

A fellow believer at my work helped me get started in political
research. He was shocked to find out that I only voted during
presidential elections. I knew little or nothing about the other
candidates or issues. He never accused me of sin but asked me to
consider taking the role of voting seriously. God brought
several verses to mind which worked conviction followed by
confession of sin, and a new desire to do my Lord's will in this
area.

Luke 20:25 told me to give to our government those things which
it demanded, and to God those things that He demands. That this
command went beyond taxes to include my vote, however, were due
to other Scriptures. Romans 13:4 and 13:6 state 3 times that the
civil servant is God's servant. The realization that the
U.S. government was not set up like the old Roman (Emperor)
monarchy sunk in. Christians designed our civil governments with
its citizens as the human civil authority (via the vote) under
God. I, Harry Rockefeller, am a civil servant here in the U.S.A.
To whom God has given much, much is required. To him that knows
to do good and doesn't do it sins. I could no longer neglect
voting with a clear conscience.
