The OT Law in the Life of the Church

Today’s blog is on a subject that is dear to my heart. What is the role of the OT Law in the life of the church? When I first had the desire to preach/share the gospel with people, I searched for a method. One of the methods that I came across was promoted by a man named Ray Comfort who lives in California. He called his method, “The Way of the Master.” I read his book, “Hell’s Best Kept Secret.”

In his book Ray speaks of the evangelist as being a salesman and gives four principles for selling: relate to the person, create on opportunity, convict of sin, reveal Jesus Christ.1 However, the majority of the book does not focus on who Jesus Christ is or His death, burial and resurrection, but on the third principle which is conviction.

“The way to produce conviction in the heart of a sinner is to take him through the Ten Commandments.”2 According to Ray Comfort, using the ten Commandments to bring conviction, is Hell’s Best Kept Secret. He describes the Ten Commandments as being like ten great cannons pointed at the sinner.3

It was early in 2010 when I read this book. I had been following the Lord Jesus Christ and reading His word daily for about seven years when the Lord gave me the desire to share the gospel with people. I saw logic in using the Law to Convict the sinner and liked the structured approach taught by ray Comfort in the Way of the Master. Therefore, I took off and ran with it. I connected with others who were using this method and went on mission trips preaching in open-air.

All the while something about using the Law this way nagged me. I had been reading the scriptures daily and kept reading them daily. I knew that there were many more laws given in the Pentateuch4 than the Ten Commandments. The apostle Paul did not believe that he or any other Christian was under the Law.5 The question that I kept asking (silently); “Why the Ten Commandments and not these other Laws?” In fact, there are more than six hundred commandments given in the Pentateuch.6

I was told that there were different types of laws given in the Pentateuch: ceremonial laws, civil laws and moral laws. I was told that we are no longer under the ceremonial laws or civil laws to keep them, but solely under the moral laws. This really did not make since to me for two reasons:

1. There is not a clear distinction in scripture between ceremonial, civil and moral laws; in the way that they are given, they are all moral.

2. I found nothing in scripture that said that the ceremonial and civil laws are done away, but we must keep following the moral laws.

What is the role of the OT Law in the life of the church?

It wasn’t until I understood covenant that I understood the role of the OT Law in the Life of the church. Covenant is a major theological theme throughout the Pentateuch7 and not only the Pentateuch, but the entire Bible. Covenant: “a solemn commitment guaranteeing promises or obligations undertaken by one or both covenanting parties.”8 There are several covenants in scripture, but the major theological covenants are: Adamic, Noahic, Abrahamic, Mosaic, Davidic and the New Covenant in Christ Jesus. In order to understand the role of the OT law in the life of the Church, you must first know what covenant(s) you as believer in Jesus Christ are under.

I am a gentile, that means that I am a non-Jewish person. I am a Christian, that means I follow Jesus Christ as Lord and put my trust solely upon Him for salvation. The Mosaic covenant was given by God to the Israelites, in the desert, at Mt. Sinai, through a mediator named Moses.9 I have never been an Israelite. The OT Law is a covenantal law, if the Israelites kept the Law, God would bless them with physical blessing and if they did not keep the Law, God would curse them with physical curses.10

The prophet Jeremiah speaking for God, spoke of a New Covenant to come.11 It is this New covenant that was ratified by the blood of Jesus Christ on the cross and promised to all who repent and believe, both the Jew and the Gentile.12 Listen to what the writer of Hebrews says about this, “When He said, “A new covenant,” He has made the first obsolete. But whatever is becoming obsolete and growing old is ready to disappear.”13 Not only were gentiles never under the Mosaic covenant with the laws to keep them; that covenant is now obsolete, because there is a New Covenant in Christ Jesus.

“What then? Shall we sin because we are not under law but under grace? May it never be!”14 Christ has given many commandments for us to follow as Christians; some OT laws He restates, some He modifies, some He intensifies, some He changes and some He does away with all together.15 Take for example the eating of certain foods in Mark 7:14-23. Have you ever eaten a Ham Sandwich? It was forbidden in the OT Law.16

Therefore, since Christians are not under the OT laws to keep them, what is the role of OT Law in the life of the church? The overarching principle that the OT law teaches is that God is Holy.17 Therefore, the role of the OT Law in the life of the church is to teach us the Holiness of God.

Suffering and Death in the ICU

Suffering: The state of undergoing pain, distress, or hardship.[1]Death: The end of the life of a person.[2]Intensive Care Unit: A department of a hospital in which patients who are dangerously ill are kept under constant observation.[3] I cannot continue doing what I have done for the past 21 years. My last day in the intensive care unit will be January 4, 2019. I will be transitioning to Cardiac Rehabilitation. This will be a completely different type of nursing. Cardiac Rehabilitation combines my love of aerobic exercise, knowledge of cardiology and love of people suffering with heart disease. I will be able to invest in their lives in a way that I was never able to do before.  These past 5 days are an example of what my work has been like for the past 21 years: I worked 4, 12 ½ hour shifts. I took care of 10 persons, all of whom suffered but some greater than others. A woman 10 years younger than I suffered a myocardial infarction (heart attack); a woman suffered greatly in the i…

Please, Please, Please Open Your Mouth and Preach the Gospel!

Please, Please, Please open your mouth and preach the gospel! Recently I was asked to do two things: 1) Think back to my own experience of how I was evangelized and describe the experience. 2) If I could go back and give advice to the person or people who ministered to me what would it be?  I began running as a young child. At the age of 5, I ran my first mile with my dad. At the age of 10, I wanted a pair of running shoes like the big runner’s wear. My dad challenged me, if I could run 5 consecutive miles at less than 8 minutes per mile he would by me a pair of running shoes. I met the challenge and he bought me the shoes. While at the runner’s store there was a flyer for an upcoming 10k race. My dad signed us both up for the race. The next year my dad was too busy with work to run with me, but we had new neighbors across the street. I noticed that this man would come home every evening and go for a run. I began running with him, at the time he was pursuing a doctorate at D. T. S., …

Evangelism and Discipleship

The defining mission of the church is to make disciples of all the nations, initiate the new disciples into fellowship through the ordinance of baptism in the name of the Triune God and teach them to observe all that Jesus commanded the first disciples; doing so by the power of the Holy Spirit. For this reason, Matthew 28:18-20 has been called the great commission because Jesus, who has all authority in heaven and on earth (Mt 28:18) commissioned his disciples to do just that. There is an utterance of this great commission at the end of each gospel account and the beginning of Acts. (cf. Mk 16:15, Lk 24:46-48, Jn 20:21, and Acts 1:8) Why? Because evangelism and discipleship are the church’s purpose for existing. For this reason, evangelism and discipleship cannot be separated. They are wholly dependent on one another. Jesus did not commission his disciples at the beginning of his ministry, but at the conclusion, and before his ascension. However, He did send them out on practice evang…
