The old covenant was a conditional works-based promise between man and God. It was meant to show the holiness of God, and how far short man falls in his own efforts. Jesus fulfilled the old covenant, establishing a new covenant between Christ the Son and God the Father. Through faith and grace we become heirs of this new covenant of freedom. However, many believers are still living under a performance-based old covenant mentality, not fully claiming the holiness and righteousness made available to us through Christ.
