Beware of men; for they will deliver you up to councils, and flog you in their synagogues, and you will be dragged before governors and kings for my sake, to bear testimony before them and the Gentiles. When they deliver you up, do not be anxious how you are to speak or what you are to say; for what you are to say will be given to you in that hour; for it is not you who speak, but the Spirit of your Father speaking through you.
Those on the side of truth have always and will always face persecution. Thankfully, the burden of truth grows lighter with time, but the burden of lies, no matter how light at the start, grows heavier with time.
A truthful person has more memory space than a liar. Naturally, their brains are faster, because they do not have to continually sift through heavy past tales. That memory space is available for prompt feedback upon interrogation.
Preparation for any interrogation is usually preparation to lie. If you hold the truth, you are always ready.
