For a Christian to say that they hate Israel is to say they hate their own brethren. When a Gentile from another nation receives the Lord, they are grafted in to God’s family and become one of the house of Israel. They are grafted in, because they received the Lord. They were once considered a wild olive tree. Romans 11:17 says, “And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakest of the root and fatness of the olive tree.”
At one time, Jews didn’t associate with anyone that they considered beneath them. Look at what the Samaritan woman said to Jesus when he spoke to her. John 4:9 says, “Then saith the woman of Samaria unto him, How is it that thou, being a Jew, askest drink of me, which am a woman of Samaria? for the Jews have no dealings with the Samaritans. It was an unlawful thing for a man that was a Jew to keep company, or come unto one of another nation. Until one day Peter saw a vision from the Lord. He saw a great sheet knit at the four corners let down to the earth on it were all manner of fourfooted beasts of the earth, wild beasts, creeping things, and fowls of the air. God told Peter to kill and eat one of the beast. Peter said no because they were unclean, but God told him not to call anything common or unclean, that he said was clean. God was referring to mankind. He later learned this lesson when he went to the house of Cornelius, a devout man that feared God.
It doesn’t matter what nationality or what race you are, if you have accepted Christ as your Lord and Savior then you are of the household of Israel. In Ezekiel 37:19-22 God instructed Ezekiel about Israel and other nations that held the children of Israel. He said,”Thus saith the Lord God; Behold, I will take the stick of Joseph, which is in the hand of Ephraim, and the tribes of Israel his fellows, and will put them with him, even with the stick of Judah, and make them one stick, and they shall be one in mine hand. And the sticks whereon thou writest shall be in thine hand before their eyes. And say unto them, Thus saith the Lord God; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land: And I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all.
Ezekiel 37:12-23 Therefore prophesy and say unto them, Thus saith the Lord God; Behold, O my people, I will open your graves, and cause you to come up out of your graves, and bring you into the land of Israel. And ye shall know that I am the Lord, when I have opened your graves, O my people, and brought you up out of your graves, And shall put my spirit in you, and ye shall live, and I shall place you in your own land: then shall ye know that I the Lord have spoken it, and performed it, saith the Lord. The word of the Lord came again unto me, saying, Moreover, thou son of man, take thee one stick, and write upon it, For Judah, and for the children of Israel his companions: then take another stick, and write upon it, For Joseph, the stick of Ephraim and for all the house of Israel his companions: And join them one to another into one stick; and they shall become one in thine hand. And when the children of thy people shall speak unto thee, saying, Wilt thou not shew us what thou meanest by these? Say unto them, Thus saith the Lord God; Behold, I will take the stick of Joseph, which is in the hand of Ephraim, and the tribes of Israel his fellows, and will put them with him, even with the stick of Judah, and make them one stick, and they shall be one in mine hand. And the sticks whereon thou writest shall be in thine hand before their eyes. And say unto them, Thus saith the Lord God; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land: And I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all. Neither shall they defile themselves any more with their idols, nor with their detestable things, nor with any of their transgressions: but I will save them out of all their dwellingplaces, wherein they have sinned, and will cleanse them: so shall they be my people, and I will be their God.
Acts 10:9- On the morrow, as they went on their journey, and drew nigh unto the city, Peter went up upon the housetop to pray about the sixth hour: And he became very hungry, and would have eaten: but while they made ready, he fell into a trance, And saw heaven opened, and a certain vessel descending upon him, as it had been a great sheet knit at the four corners, and let down to the earth: Wherein were all manner of fourfooted beasts of the earth, and wild beasts, and creeping things, and fowls of the air. And there came a voice to him, Rise, Peter; kill, and eat. But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean. And the voice spake unto him again the second time, What God hath cleansed, that call not thou common. This was done thrice: and the vessel was received up again into heaven. Now while Peter doubted in himself what this vision which he had seen should mean, behold, the men which were sent from Cornelius had made enquiry for Simon’s house, and stood before the gate, And called, and asked whether Simon, which was surnamed Peter, were lodged there. While Peter thought on the vision, the Spirit said unto him, Behold, three men seek thee. Arise therefore, and get thee down, and go with them, doubting nothing: for I have sent them. Then Peter went down to the men which were sent unto him from Cornelius; and said, Behold, I am he whom ye seek: what is the cause wherefore ye are come? And they said, Cornelius the centurion, a just man, and one that feareth God, and of good report among all the nation of the Jews, was warned from God by an holy angel to send for thee into his house, and to hear words of thee. Then called he them in, and lodged them. And on the morrow Peter went away with them, and certain brethren from Joppa accompanied him. And the morrow after they entered into Caesarea. And Cornelius waited for them, and he had called together his kinsmen and near friends. And as Peter was coming in, Cornelius met him, and fell down at his feet, and worshipped him. But Peter took him up, saying, Stand up; I myself also am a man. And as he talked with him, he went in, and found many that were come together. And he said unto them, Ye know how that it is an unlawful thing for a man that is a Jew to keep company, or come unto one of another nation; but God hath shewed me that I should not call any man common or unclean.
