The important point here is that there is only one God, the Lord of Love, the Source of all. He's very real, and he does interact with us and he does incarnate on earth to attract the living entities back home, back to Godhead.

One of the main points of "philosophical" difference between Krsna consciousness and Christianity as a whole is the christians believe a soul incarnates only one time on earth, gets it's chance to be good or bad and then goes to heaven or hell after that. Hindus, however, tell us that a jiva soul becomes trapped in the cycle of birth and death, having turned away from the Lord and become enamoured with god's external energy called Maya. That soul will get innumerable chances to seek god, and when they eventually do, they are then able to go back to godhead. It may not be as easy as it sound however, for god is not so cheap to obtain, and we are so contaminated by our lust and greed here that we are often unable to let it go in our hearts.

What is the way back to God then? In order to cross over the ocean of birth and death, we must pray for devotional service of the Lord, selfless service based upon love and affection for god himself. How can we feel love and affection for someone we do not know? We can't and so we must learn something about the Supreme Personality of Godhead. True he has many names and many forms but at the same time he has one form full of all auspicious qualities that he will reveal to us if we desire to know him.
