In the Spirit's Power - William W. Prescott

Caesar cannot help that. He can prevent a man’s
thought from expressing itself in any way to injure
his fellowman; but God looks through stones and
bars into the heart, and in His sight that man is still
a sinner, though he is kept from manifesting it by
the power of the sword.
Temporal v. Eternal
Further, God deals wholly with things that are
eternal; Caesar with things that are temporal. God
Himself is eternal. “The eternal God is thy refuge,
and underneath are the everlasting arms.” It was
through the eternal Spirit that Christ offered
Himself for us. It is eternal life that He holds out as
a reward. Caesar knows nothing of such things as
that. He is not supposed to know whether a man is
on the road to heaven or hell. He is not supposed to
make inquiry where he proposes to spend his time
in the future. All he is to ask is, “What are you
doing to-day?” Caesar’s punishment has nothing to
do with eternity. He simply deals with temporal
gifts, temporal punishments, temporal rewards;
nothing more.
