Hi whoever you are I think you havent read all the scriptures properly.According to Gurucharita and also in Bhagavadgita,Lord Krishna tells Guru is God.To reach me you need to have proper guide who is guru and who had already attained brahaman and crossed those stages.Even Lord Krishna and Rama had Gurus even inspite being gods themselves.There is no wrong in worshipping Jesus or Prophet Mohammed ,they are gurus.There is also a saying if Guru gets angry with you no one can save you even god.There is no wrong in worshipping them and even Idol worship is also not wrong which Islam doesnt encourage.Ramakrishna Paramahamsa did Idol worship and he spoke with godess Kali.Everything which is done with faith and devotion is accepted by god.
