1 Corinthians 15:14,17
And if Christ has not been raised, then our preaching is in vain and your faith is in vain. And if Christ has not been raised, your faith is futile and you are still in your sins.

Tell the world! Tell the young. Tell the poor. Tell the aged. Tell the ignorant. Tell the sick. Telle the dying. Tell them all about Christ.
