A Thread To Tread Upon

Where is the line between passionately defending the Truth, and being rude?

Obviously,
I'm sure you realize (or thought), as
Anyone who's rational with
Common sense demands,
That condescending words can hold no love.



¹⁴ God, arrogant people have attacked me;
    a gang of ruthless men seeks my life.
    They have no regard for You.
    ¹⁵ But You, Lord, are a compassionate and gracious God,
    slow to anger and abundant in faithful love and truth.
    ¹⁶ Turn to me and be gracious to me.
    Give Your strength to Your servant;
    save the son of Your female servant.
    ¹⁷ Show me a sign of Your goodness;
    my enemies will see and be put to shame
    because You, LORD, have helped and comforted me.
Psalm 86:14-17 (Emphasis Mine)


But speaking the truth in love, let us grow in every way into Him who is the head —Christ.
Ephesians 4:15
