Actually the bad news is we can not keep them... the GOOD NEWS is that Jesus kept them for us..
Praise the Lord for that! In the New Testament when Jesus spoke of the commandments concerning murder and adultery, we should remember that he was specifically addressing the self-righteous religious leaders of his day. They considered themselves perfect and keeping the Mosaic laws completely. Jesus turned them on their ears when he explained the spirit of the law - they only considered the letter of the law - hence to call your brother a fool was to murder him "in your heart" and to lust after a woman - any woman - was to commit adultery "in your heart".
The law was therefore the "schoolmaster" to point us to our sinfulness and our desperate need of a savior.
Galatians 3:23-25 (King James Version)
23But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
24Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
25But after that faith is come, we are no longer under a schoolmaster.
