I would let the Quran speak for itself.

Here is the translation of verses that you are referring to. Read them and if you have questions afterward, please forward them to me.

2:6 As opposed to Muttaqeen, there are rejecters who see the right path clearly, yet do not adopt it, being impelled by their obstinacy, jealousy, vanity, and vested interests (2/89-90, 109, 27/14, 35/42-43, 47/32). They do not follow this path themselves, and also prevent others from following it (6/26, 41/26, 43/32). Whether or not the K’afireen are warned about the disastrous consequences of following the wrong path, it is the same for them. They will never adopt the right path (36/70). 

2:7 As a result of their outlook and actions, the K’afireen lose their capacity for observation and comprehension. They, thus, deprive themselves of the real joys of life, falling headlong into the inferno of devastation. Indeed how pathetic is their end! 

2:257

257        Allah is the Guardian of Momineen and brings them from darkness towards light. Oppressive forces are the guardians of those who reject Allah’s Laws and take them from light into darkness. Ruin and disaster are their everlasting end.

2:254 Differences amongst human beings can be overcome if they subordinate their wills to Divine Guidance and establish a Quranic Order. To do that financial support is required. O Jama’at-ul-Momineen! make every effort to establish this order before it is too late and the time comes when no bargaining, friendship, or intercession will be possible. And those who deny the truth are the ones who bring suffering to themselves.
