Brahma is not the God of Christianity, the Trimurti is the God of Christianity. Brahma, Vishnu, and Shiva are the three aspects of the one God, just like the triune God of Christianity. So we must look at the totality of attributes of Brahma, Vishnu and Shiva to see that these attributes are remarkably similar to the God of Christianity.
I'm not going to give you the Biblical equivalents because that is just lazy , but here are the attributes of the Trimurti God from the Bhagavad Gita:
"The beginningless, and the Supreme Lord of the universe" "Discrimination, knowledge, non-delusion, Forgiveness, truthfulness, control over the mind and senses, Pleasure, pain, birth, death, fear, fearlessness;Nonviolence, equanimity, contentment, Austerity, charity, fame, and ill fame; All these diverse qualities in human beings Arise from Me alone." "I am the origin of all. Everything emanates from Me." "The eternal divine spirit, the primal God, The unborn, and the omnipresent." "I am also the beginning, the middle, and the end of all beings" "You are the knower, the object of knowledge..." " O adorable Lord, I seek Your grace " " Brahman as the omniscient" "....transcendental or beyond the material reality"
