John Willis Zumwalt said this quote

The sad reality is that there are many Christians who are “saved”, “heaven bound,” and “hell proofed” who do not care about the souls of the lost. What a beautiful contrast our Lord Jesus Christ is! His passion for souls brought Him from Heaven to earth, His Passion for souls motivated His compassionate activity. His passion for souls pressed Him to a rough cross where He surrendered His life to save the lost.
