Here it is predicated that when Islam spreads far and wide, it would happen at various times and in diverse regions, that a group out of the people of the Book would strive that you should emerge from the circle of Islam, and despite having recognized the Truth and the light you should deny them after having believed. In the text it is not expressly stated what your reaction would be or should be. But the latter portion of the verse indicates that they would make their utmost efforts and would employ force to pull you out of the fold of Islam and you would resist them. Nevertheless you must not use any kind of force or compulsion against them. You should forgive them and forbear. Surely Allah has full power to do all that He wills. He will bring about a change in the juxtaposition between you.
