Why does man need protection? God thought enough of us to put mankind under the watchful guard of the law. Man's propensity is to live out of control, causing havoc to ourselves and others. The law was given to reveal sin and to protect us until the Seed, Jesus Christ would come. The law or guard directed us to our only means of justification which comes by faith in Christ. With saving faith we can live holy and righteous lives not because we are under guard but because we are under grace and that is the best protection of all.
