If you suffer from moral anemia, take my advice and steer clear of Christianity. If you want to live a life of easy-going self-indulgence, whatever you do, do not become a Christian. But if you want a life of self-discovery, deeply satisfying to the nature God has given you; if you want a life of adventure in which you have the privilege of serving him and your fellow men; if you want a life in which to express something of the overwhelming gratitude you are beginning to feel for him who died for you, then I would urge you to yield your life, without reserve and without delay, to your Lord and Saviour, Jesus Christ.
