“Mish Maoul.” In Arabic, the phrase means unbelievable. A Spanish word I use frequently is “increible”. 1 Thess. 1:5 says, “When we told you the good news, it was with the power and assurance that come from the Holy Spirit, and not simply with words.” The unbelievable was made believable through preaching and testimony empowered and assured from the Holy Spirit. Such a message communicated only with words remains unbelievable, but the message of the gospel is not simply words. Jude 15 says one day that which is unbelievable will be believed by all. All will be convicted.
Consider four things that are unbelievable without Christ. Christian faith makes these believable.
