  We consider the heavy quark limit of Coulomb gauge QCD, with the truncation
of the Yang-Mills sector to include only (dressed) two-point functions. We find
that the rainbow-ladder approximation to the gap and Bethe-Salpeter equations
is nonperturbatively exact and moreover, we provide a direct connection between
the temporal gluon propagator and the quark confinement potential. Further, we
show that only bound states of color singlet quark-antiquark (meson) and
quark-quark (SU(2) baryon) pairs are physically allowed.
