Introduction To Christianity - pg. 104

It is only here, where the God who is recognized as Lord
of all has voluntarily chosen the final degree of powerlessness
by delivering himself up to his weakest creature, that the
Christian concept of the almightiness of God can be truly
formulated. At this point simultaneously a new concept of
power and a new concept of lordship and dominion is born.
The highest power is demonstrated as the calm willingness
completely to renounce all power; and we are shown that
it iss powerful not through force but only through the
freedom of love, which, even when it is rejected, is stronger
than the exultant powers of earthly violence. Here and only here
does that revaluation of criteria and dimensions which
made itself heard earlier in the antithesis of maximum
and minimum finally come into its own.
