For he indeed accepted our exhortation, but being himself very earnest, he went out to you of his own accord.

according to my earnest expectation and hope, that I will in no way be disappointed, but with all boldness, as always, now also Christ will be magnified in my body, whether by life, or by death.

And above all things be earnest in your love among yourselves, for love covers a multitude of sins.
