waters of the lake flow with swift rush into the Rhone. And we were both
greatly interested in the strange sight which has impressed so many
travellers. There are two rivers whose waters come together here, the
Rhone and the Arve, the Arve flowing into the Rhone. The waters of the
Rhone are beautifully clear and sparkling. The waters of the Arve come
through a clayey soil and are muddy, gray, and dull. And for a long
distance the two waters are wholly distinct. Two rivers of water are in
one river-bed, on one side the sparkling blue Rhone water, on the other
the dull gray Arve water, and the line between the two sharply defined.
And so it continues for a long distance. Then gradually they blend and the
gray begins to tinge all through the blue.

I went to the guide-book and maps to find out something about this river
that kept on its way undefiled by its neighbor for so long. Its source is
in a glacier that is between ten thousand and eleven thousand feet high,
descending "from the gates of eternal night, at the foot of the pillar of
the sun." It is fed continually by the melting glacier which, in turn, is
being kept up by the snows and cold. Rising at this great height, ever
being renewed steadily by the glacier, it comes rushing down the swift
descent of the Swiss Alps through the lake of Geneva and on. There is the
secret of purity, side by side with its dirty neighbor.

Our lives must have their source high up in the mountains of God, fed by a
ceaseless supply. Only so can there be the purity, and the momentum that
shall keep us pure, and keep us _moving_ down in contact with men of the
earth. And we must keep closer to the source than is the Rhone at Geneva,
else the streams flowing alongside will unduly influence us. Constant
personal contact with Jesus is the beginning ever new of service.
