There is only one new testament book where the word love is not mentioned - which one?

The answer is the book of Acts. My second question which I am pondering is "do we present the Gospel clearly to the unbeliever" - I was saved at University - in the first 2 years of uni I knew many christians who kept telling me how much God loved me. The result was I enjoyed the free sandwiches, coffee, christian girls with a false thought that I was generally on the way to heaven as God loved me. Thank God that I met a christian in year 3 in industry who told me "are you righteous in Christ" and gave me a book about the revival in South Korea. I was radically saved. How do we more clearly present the truth of Jesus is Lord and the need for righteousness by faith and avoid the bumper sticker "God loves you - relax in the traffic" etc
