John 3:17

For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.

This world is lost and confused, and in that confusion is seeking the answers.  God sent Jesus not to condemn but to save, and now we are to follow that example.  We may not always know the right things to say to reach the lost, but we are meant to plant a seed.  Our experiences and what we have learned in this life will help us to reach out in compassion and show the Love of Christ to others.
