Peace on earth is impossible as long as there is sin in the world. For this reason, we are commanded in Romans 12:18 to live peaceably with all ... if possible, so far as it depends on you.
The reality is that under the current dispensation, the expression of love is still being restricted by the radiation of evil. Yet this must not be allowed to restriction of love. People may reject our peace, but it must always be proffered.1
18 S'il est possible, autant que cela dépend de vous, soyez en paix avec tous les hommes.
