Hi Rico and welcome!!
Fervor and zeal are strong emotions, aren't they? :-))
thanks for both, in ministry and poetry.
re: ministry ...
those with the call to preach often, mistake that call for a call to see results, and measure their obedience and effectiveness in terms of results, when the preacher is not asked to measure them nor wished to do so.
Just do as your calling dictates and be obedient to it both when/if multitudes respond as well as when zero do.
Results are not a measurement one way or the other, to the preacher and He is responsible
for them, when and if any.
And in the final analysis, it may not have been converts He wanted from you, just the obedience of a pure heart...
be of good cheer, young friend...
preach on til He says otherwise
and write your poetry not about rejection
of men but about being loved by Him...
