Jesus speaks of brother turning against brother in betrayal; of father standing in hatred against his own child; of children despising and sending their own parents to death. He speaks of Christians being arrested, taken into court, accused — for His sake — presumably of all sorts of false charges.
And Jesus encourages us, “Do not worry about what you are to say; when the time comes, the words you need will be given you; for it is not you who will be speaking; it will be the Spirit of your Father speaking in you.”
Wait for God’s timing. Do not fret over what you are to say when someone — perhaps even someone who professes to love you — betrays you. In His timing, God gives you His Word to speak to that someone. Rest assured; you are not on your own.
