Translation:

108. Say: "O ye men! now Truth hath reached you from your Lord! Those who receive guidance do so for the good of their own souls; those who stray do so to their own loss: and I am not (set) over you to arrange your affairs."

Notes (Tafseer)

1490. The Furqan, the Criterion between right and wrong, has been sent to us from Allah. If we accept guidance, it is not as if we confer favours on those who bring us guidance. They suffer unselfishly for us, in order that we may be guided for our own good. On the other hand, if we reject it, it is our own loss. We have a certain amount of free-will, and the responsibility is ours and cannot be shifted to the Prophets sent by Allah.
