There is no human who live a life without sin but JESUS.The world is fill with sin.it take the grace of God to be save. The ultimate commandment that compile all other commandment in any religions you could name is, as Jesus said, "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets."

To love God, who we cannot see with our eyes, whose voice we could not heard by our ears, is much harder. And we have to love God with all our heart, all our soul and with all our mind.
