As a Christian we are called to read and believe the bible and obey God through faith and love, not the hypocrisy of legalism and the dead works of the law.
Ro 7:6 But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter. 7 ¶ What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.

The reason why people cannot keep the law is because they do not love from the heart. Through failure we learn we have a problem in areas of our life which needs attention. The ministry of the church is to help the body grow and mature, to pick themselves up when they fall, and learn the power of life is the relationship with each other and God through Jesus.
As soon as we think we have arrived we fail, because we rely on what we are and not grace and love working within. I have seen christians who had their lives so worked out, they said they no longer needed the Lord. A tree soon rots within, and the fruit ceases to come. There are no simple rules because you are talking life, relationship and spiritual experience.
