  We reveal a new way in which the Lorenz gauge condition is related to the
electric charge conservation, in a universe where electrically charged point
particles are created and annihilated. We derive our results using time
symmetric electrodynamics, relying on observations made by Jacov Frenkel (in
1925) and John Archibald Wheeler (in 1940). Both the Lorenz gauge condition and
the electric charge conservation are expressed as closed path integrals in
Minkowski space. The integration path is the same, it is the sum of all
"Wheeler electrons".
