Firstly the verses point at the universal Message of God which is contained in the glorious Qurän; admonishing Man in going astray, and inviting him to God's Mercy and forgiveness. Qurän is said to be a healing ointment for our spiritual diseases, and it is also a guiding means, and a Mercy for those who believe it.

      By that, which is said here to be in the breasts (hearts); our spiritual contaminations are wanted, such as; stinginess, jealousy, hatred and rancour, cowardice and timidity, and polytheism and hypocrisy, and etc., that make the mental or spiritual diseases of Man. This Qurän provides a healing for such mental and spiritual diseases. But if the patient accepts it, the remedy acts, and they will be cured; if they reject the divine prescription, it will cause their spiritual death!

      The verse actually points to 4 stages of development and evolution of Man, that Qurän provides, namely:ِ

      1ِ The stage of preaching and admonition.

      2ِ The stage of cleaning the inner self from the spiritual contaminations, as mentioned above.

      3ِ The stage of guidance and leading.

      4ِ And the last stage is, when Man has obtained the merits for receiving God's Mercy.

      It is worthy of note that all the said four stages can be attained by means of the Glorious Qurän.

      The next verse implies that Qurän is the best of all the bounties of God. Therefore, Man should grasp the chain of god, which is His Book, if he wants to be connected with his Lord. This will lead him in a straight path to God's Mercy and Grace. Instead of rejoicing in power and wealth amassed, Man should rejoice in God's Grace and mercy and in His Book of guidance and light.

      As to the difference between Allah's Grace and Mercy; some commentators understand the Grace, to be God's physical bounties, and the God's mercy as His spiritual gifts.
