Honor the Name of God!
First of all you must know and understand that it is by grace you have been saved. It is not because of your good works etc.. But if you count yourself religious and still rely on the law to be forgiven and saved, than yes, you must read them and understand and keep. Every one of them.
Secondly I would like to add that for the word “law” in Hebrew in regard to these 10 commandments correct translation should be “principles.” God gave not only to the Jews but to whole world principles by which if lived, than there can be love, joy, peace and other blessings in person’s life.
Thirdly, any command or principle is with much more greater emphasis from that how we often see and comprehend them. For example it is said: “you shall not murder.” We directly imagine murdering human being. But actually is said also: “if you are angry at your brother or sister…” you are broken this one commandment already. You are murderer in your heart.
Furthermore, it is extremely important to understand that the main reason why the Law was given is, to show people that they are sinful and they are in great need of Redeemer. Galatians 3:19.
Since we have Redeemer already (to everyone who accepts Him and begin to follow His principles), each and every Law, commandment and decree, what ever there may be, are fulfilled by Jesus Christ. He did it for you on the Roman cross. Now, as He through the Holy Spirit begins to work in you, you will be made able to love GOD and love others as yourself.
You will be able to walk with God.
For those who love God and are loved by God, there are no really Law to follow for the entire Law is fulfilled in keeping this one command: "Love your neighbour as yourself" (Galatians 5:14).
The law was given through Moses; grace and truth came through Jesus Christ. John 1:17.
Christ redeemed us from the curse of the law by becoming a curse for us (Galatians 3:13).
If and still there is any doubt in your heart, see all Commandments (just to understand that not even one person has been able to keep them and will be not, for all people are sinful from birth and are in need of Saviour).
In every way seek the Truth, for Christ is the culmination of the Law so that there may be Righteousness for everyone who believes. Romans 10:4.
All who do love are from God and God's Principles for godly living automatically are in his/her heart, for God Himself put them in. All people are saved exclusively by faith alone, by grace alone in/ through Christ alone.
The life and godly walking according the God's advices will be what brings peace, joy and happiness. Not the concentration on the so called 10 commandments.
People who are free from the Law are enabled to live, and serve God from the bottoms of their hearts; they are able to love and do more than those who follow and try to live according to the Law.
Anyway, here is the good, holy and perfect Law:
This commandment commands to revere God by not using His name in vain. We must respect Him in all our ways and do not use His name in public or when we are alones with disrespect, falsehood and emptiness; in abusive and irreverent jargon. If we have established our relationship with Him, than we must learn to show proper respect to His name. Profanity is the common way how people desecrate and despise the name of living God. The name of God is despised also of all times religious leaders who, put it simple, has acted in the name of God just "to obtain wealth, power and dominion."
Paul in Romans 2:17-24 explains how God's name is blasphemed among the Gentiles by religion leaders.
The same is also today. If we have a humble, thankful, loving heart to God and His commandments - to love the God and each other - than we are fulfilled His requirements; and we will be careful not to disgrace and abuse the name of our loving Father. If we have a proud, vainglorious boasting in God and we profess His name outwardly, than we are just a hypocrites as that time Jewish leaders were, and some of our time religious leaders are; and the truth is not in us.
What can be more sad than that how our (and all times) religious leaders in so many ways do blaspheme and slander His Holy name! In regard to religious leaders Jesus said – "Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead and everything unclean. In the same way, on the outside you appear to people as righteous but on the inside you are full of hypocrisy and wickedness." (Matthew 23:27-28).
The name of God the Father and that of His Son must be revered, praised and glorified in every way. Jesus Christ is the only way how we can be saved and go to heaven. Christ means Saviour and Redeemer; the Annointed One. Jesus Christ is our Master and His name must be kept holy, His and our Father's name.
If we truly love the Lord our God with all our heart and with all our soul and with all our mind than we will be careful in our speach and will learn to revere and praise His name always. We will love Him will and will be careful to honor His name in every way.
"Praise the LORD. Praise the name of the LORD; praise Him, you servants of the LORD."
