You may have come across Hebrews that came off distant, or may not have trusted you so readily; Hebrews that might be standoffish with you . You must understand that you are among a nation of people who have a history of being seriously abused by YOUR people. You as an individual might be genuine, right minded, and YAH knows, your heart may be true; but, it still remains that it was YOUR people that dealt treacherously with my people for a very long time.
The government has a history of sending in agents to pretend they're of the faith, or down with whatever organization that involves Hebrews coming together. Try not to expect to be so quickly embraced when you fellowship with Hebrews, their suspicion of you is not without cause. Their distrust is not without cause. Think of the history between our peoples.
If you are genuine, continue to serve the most High through Yahoshua. Do not become offended by those of us that take awhile to embrace you. Do not forget those 9 Hebrews in the church who openly embraced Dylan Roof. He came in, prayed with them, read scriptures with them; and then turned around and slew all of them.
This is just an example. It may not be you with that kind of spirit; but understand that when it comes to the so-called Negroes, the spirit of darkness dwells heavily within your people.
