If Jesus Christ was who He claimed to be, and He did die on a cross at a point of time in history, then, for all history past and all history future it is relevant because that is the very focal point for forgiveness and redemption.
Josh McDowellI am not a Christian because God changed my life; I am a Christian because of my convictions about who Jesus Christ is.
Josh McDowellThere was a time when only specialized Christian missionaries needed to be able to defend the gospel of Jesus Christ against the attacks of Islam. Today every Christian has an opportunity and obligation to present the gospel effectively and in Christian love to the Muslims who have permeated our Western society. When your neighbor, your mechanic, your favorite basketball player, your employer or employee, or even your children's friends could very well be Muslims, the need for proper understanding and an effective Christian witness is abundantly clear.
Josh McDowellMany people entertain the idea that Christianity,like almost any other religion,is basically a system of beliefs-you know, a set of doctrines or a code of behavior, a philosophy, an ideology. But that's a myth. Christianity is not at all like Buddhism or Islam or Confucianism. The founders of those religions said (in effect), 'Here is what I teach. Believe my teachings. Follow my philosophy.' Jesus said, 'Follow me'(Matthew 9:9). Leaders of the world's religions said, 'What do you think about what I teach?' Jesus said, 'Who do you say I am?'(Luke 9:20)
