Apart from showing the existing arguments in a more profound way (ones derived from prophecies, miracles and Jesus’ Resurrection) attempts are undertaken to construct new ones. Praxiological argumentation, referring to, among others, sanctity of life, love, hope and testimony of Christian life are especially convincing for the contemporary man. The aim of the present article is to present the testimony in relation to faith in its motivational aspect. The author tries to answer the question: When does the testimony of Christian life become a motive for faith? The problem is presented in four points. The following issues are analysed: Jesus as a credible Witness of God; the Person of Jesus Christ as the object and source of Christian testimony; forms of testimony; and recognition of testimony and efficiency of motivation. A comprehensive discussion of the above issues has allowed presentation of the testimony of Christian life as a motive for faith.plAttribution-NonCommercial-NoDerivs 3.0 Polandhttp://creativecommons.org/licenses/by-nc-nd/3.0/pl/Jezus Chrystuschrześcijaństwoświadectwowiarygodnośćakt wiarywiaraświadectwo chrześcijańskieJesus ChristChristianitytestimonycredibilityact of faithfaithChristian testimonyArticle
