Can man be perfect on earth

I have asked the question many times and I want to open this one up to a forum of the masses: Can man be perfect while on Earth? Taking the Christian approach this question, Matthew 5:48 reads that Christ commands us to be as perfect as Heavenly Father. Is this possible? Please respond, and members of other faiths, like Islam and Judaism, please give me your thoughts on this subject, I am curious to your view points on Man becoming more like their creator
