Some things are worth fighting for.
And some things are not.
So distinguish between levels of certainty.
This will help you differentiate between what is essential and what is controversial. Some things are worth dying for. Some are worth dividing for. Some things are worth debating for. Some are only worthy of deciding for.
Be as clear as the Bible is clear and be humble enough to stay as unclear as it is unclear. This will save you so many foolish disputes and arguments and help you to keep the main thing the main thing. The unity of the Spirit is based on the absolutes and essentials, not questionable deductions and interpretations of the kingdom. Pray for wisdom to discern the difference.
