Just two commandments. Lets deal with them one by one.
"Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind"
- Yet to be convinced God does exist ... it does not help with Jesus saying he is God as well and he was created by the Holy Spirit and Mary
- Love with All thy heart, soul and mind - means there is nothing left for loving others and even yourself
Thou shalt love thy neighbor as thyself
- See point 2 above ... If all your love is to God, there is no love left for you and others.
- It is a truism for all religions and even being a human being without belief (e.g. Human Rights).
So if you can not obey the first commandment, because you love others and yourself and are not convinced that God exists on top of that to give him some love as well. Even if I was forced to choose between God and someone else I love, I would choose someone else (e.g. my loving wife).
The second commandment is simply a good sound principle on how to interact with others, which has been further refined by the UN in its declaration and by others in their religions and beliefs.
That been the case, what then makes being a Christian any different to being any other religious adherent or even an Atheist (like me), other than the fact you are following Jesus' and his followers teachings in a unique way.
