All in Obeying God’s Commandments

Can we actually obey all of God's commandments? Man has been struggling to answer this question since Adam and Eve were first told not to eat from the tree of the knowledge of good and evil. And although they failed at keeping that one command God did not abandon them, but clothed them instead, and continued to love and teach them. Later, Moses came down from the mountain with even more commandments… And we all know what happened then; man continued to fail. So are we doomed to lives of failure? Is it any different today than it was then? Not really, but God has made provision for us. Are we ready to receive it?
