Christian symbols and themes have also been invoked by rap artists who do not consider themselves "Christian Rappers", and do not claim to represent any particular set of religious beliefs. Examples include MC Hammer's No. 2 single "Pray"; Richie Rich and his first single "Don't Do It"; many of Tupac's lyrics and his first posthumous record, "", the image of Tupac nailed to a cross pinned him as a hip hop martyr; and even recent hip hop/rap artists like Jay-Z with "Kingdom Come", DMX with "Walk With Me Now and You'll Fly With Me Later", Nas with "God's Son" and Kanye West with "Jesus Walks" and "Jesus Is King". However, these artists, although they may profess to be Christians, are not generally considered to be part of the Christian hip hop movement. Some Christians believe that hip hop culture in any form conflicts with biblical teachings, while others consider hip hop to be a way of reaching the youth and mainstream culture.
