John Piper said this quote
“ Have you ever wondered what it feels like to have a love for the lost? This is a term we use as part of our Christian jargon. Many believers search their hearts in condemnation, looking for the arrival of some feeling of benevolence that will propel them into bold evangelism. It will never happen. It is impossible to love “the lost”. You can’t feel deeply for an abstraction or a concept. You would find it impossible to love deeply an unfamiliar individual portrayed in a photograph, let alone a nation or a race or something as vague as “all lost people”.Don’t wait for a feeling or love in order to share Christ with a stranger. You already love your heavenly Father, and you know that this stranger is created by Him, but separated from Him, so take those first steps in evangelism because you love God. It is not primarily out of compassion for humanity that we share our faith or pray for the lost; it is first of all, love for God. ”
