“Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. And be kind to one another, tender-hearted, forgiving each other, just as God in Christ also has forgiven you” (Ephesians 4:31-32).
There is no problem-solving section of the Bible.
Sorry if that disappoints you.
What we do find across the New Testament are large servings of healthy food of the spiritual kind, instructions on how to serve God and live well and relate to one another in the close confines of the forever family. Imbedded throughout are insights on resolving collisions between the Lord’s children.
Hold on.
Do you mean to say that from the beginning Jesus expected clashes and collisions within His family? That His disciples would be torn apart by jealousies and competitions and divisions?
It would appear He did.
