That is a difficult balance to maintain. Either we are hard and immovable or weak and flexible. A mature person holds both conviction and flexibility in tension. Paul was inflexible with foundational truth. Paul wept over those who do not know Christ as Savior.
Weeping is no longer in vogue.
We live in a day of stingy compassion. We do not have any passion because we do not have any compassion. We develop hardness to the lost and the reality of hell. Therefore, we do little, if anything, to introduce people to Jesus. Paul even wept over apostates in our passage.
