Taucht ein in das Wort

Für viele ist die Bibel schwer zu verstehen – voller tiefgründiger Texte,  Symbole und historisch sowie spirituell wertvollen Geschichten. Die Fülle an Bedeutungen bleibt oft verborgen wenn man die Konzepte nicht kennt und ohne Anleitung fühlt man sich schnell überfordert. Wie soll man die Heilige Schrift wirklich begreifen wenn Sie oft leider nur einen kleinen Teil in unserem hektischen Alltag hat.
