There is a time for saying what is needed to say right now, and there is a time for saying what has always been said. There is a time for searching the annals of history for timeless truths, and there is a time for speaking specifically to the situation you’re in with the one person directly in front of you.
Do both.
For the truth of the ages is good regardless of the era and will inform the needs of the present, and the needs of the present will ultimately point towards the truth of the ages, bringing life to the lifeless, awaking the sleeping, bringing sight to the blind, and hearing to the deaf.
