For biblical Christians to change our secularized culture, we cannot keep doing the same thing while expecting different results. When I went to Cuba on various mission trips, it would have been vain for me to speak in English to people who only understood Spanish. Talking louder would do no good. I needed to speak their language to impact their lives.
The good news is, God’s Spirit knows the spiritual condition of every soul on this planet. It’s as though he were an attorney persuading the jury to choose his client. He calls us as witnesses to the stand when we fit best into his strategy. Then he leads us to give the testimony he can best use to win the case.
