have always believed that it was the Body Of Christ that was grafted into the Olive Tree but this guy makes a compelling argument to the contrary. I would appreciate your thoughts on this......
The "Olive Tree" does not represent the Church, which is His Body. Instead, it represents the "service" of believers. The Olive Tree analogy is in regard to "bearing fruit", or "service". At the time when the nation of Israel was bearing fruit the Lord called them an Olive Tree:
"The LORD called you a thriving olive tree with fruit beautiful in form. But with the roar of a mighty storm he will set it on fire, and its branches will be broken." (Jer.11:16).
The Olive Tree was an important tree for the Israelites because it was a source of food and light for them. For hundreds of years the olive was eaten as a staple food and olive oil has been used for cooking and in lamps for light. The oil of the olive was also used for anointing in religious ceremonies.
In regard to bearing fruit the Israelites were appointed to be the LORD's agent upon the earth to bring the gospel to the Gentile nations:
"For I, the LORD, love justice; I hate robbery and wrongdoing. In my faithfulness I will reward my people and make an everlasting covenant with them. Their descendants will be known among the nations and their offspring among the peoples. All who see them will acknowledge that they are a people the LORD has blessed" (Isa.61:8-9).
"Surely you will summon nations you know not, and nations you do not know will come running to you, because of the LORD your God, the Holy One of Israel, for he has endowed you with splendor" (Isa.55:5).
Due to the unbelief of many Israelites those people were bearing no fruit for the LORD so they were broken off of the Olive Tree which represents fruit bearing or service. Then when the gospel went to the Gentiles most of those who believed bore fruit for the LORD by serving Him and were therefore grafted into the Olive Tree. But even those believing Gentiles whose service came up short were saved nonetheless:
"For no one can lay any foundation other than the one already laid, which is Jesus Christ. If anyone builds on this foundation using gold, silver, costly stones, wood, hay or straw, their work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each person's work. If what has been built survives, the builder will receive a reward If it is burned up, the builder will suffer loss but yet will be saved--even though only as one escaping through the flames" (1 Cor.3:11-15).
According to Paul some of the Jews were "broken off because of unbelief." How could the Olive Tree be a symbol of the Body of Christ since the Lord Jesus said the following about those who come to Him?:
"All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out" (Jn.6:37).
Paul also told the Gentile believers that since "God did not spare the natural branches, he will not spare you either." Therefore, if the Olive Tree represents the Body of Christ then no one in the Body enjoys eternal security despite the following words found here:
"For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life" (Jn.3:16).
