~Joshua 22:5 But take diligent heed to do the commandment and the law, which Moses the servant of the LORD charged you, to love the LORD your God, and to walk in all his ways, and to keep his commandments, and to cleave unto him, and to serve him with all your heart and with all your soul.
The law in the Old Testament was no different that the law which Christ left for us to follow.
~Matthew 22:37-40 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets.
As a born-again Christian, our desire is to nurture our relationship with our Heavenly Father and become more like Christ. In so doing, our actions will speak and reflect this relationship. As we draw closer to the Lord, we have a desire to share that love with others. One who loves will not lie against another – one who loves will not steal from another. As a result, we are fulfilling the law that Christ spoke of: We draw closer to God and, in turn, reflect that relationship through our actions.
