Translation:

3. ("And to preach thus) `Seek ye the forgiveness of your Lord and turn to Him in repentance; that He may grant you enjoyment good (and true) for a term appointed and bestow His abounding grace on all who abound in merit! But if ye turn away then I fear for you the Penalty of a Great Day:

Notes (Tafseer)

1495. The enjoyment of all good and true things in life refers, I think, to the present life with its limited term, and the abounding Grace refers to the higher reward, which begins here but is completed in the life to come.
