Do we fulfill the royal law?

As children of God, we are citizens of the kingdom of God.  In this kingdom there is something that is known as the royal law.  My question to you is are you fulfilling the royal law?  It says in James 1:25 (NKJV)”25 But he who looks into the perfect law of liberty and continues in it, and is not a forgetful hearer but a doer of the work, this one will be blessed in what he does.”  So in this preeminent law of liberty is  blessing.  In other words, if we will do the the perfect law of liberty we have a guarantee from our Heavenly Father that we will be blessed.  Then what is this law of liberty?  The perfect law of liberty was proclaimed by our Lord and Saviour Jesus Christ.  It's recorded in Matthew 22:37-40 (NKJV) "37 Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ 38 This is the first and great commandment. 39 And the second is like it: ‘You shall love your neighbor as yourself.’ 40 On these two commandments hang all the Law and the Prophets.”"
