How to interpret that Allah and the angels send prayers and blessings to the believers?

Allah tells us that HE and HIS angels send prayers and blessings the believers saying: > It is He who confers blessing upon you, and His angels [ask Him to do so] that He may bring you out from darknesses into the light. And ever is He, to the believers, Merciful.(33:43 ) In before this verse in surat al-Baqarah we are informed that Allah sends prayers to some of the believers: > Those are the ones upon whom are blessings from their Lord and mercy. And it is those who are the [rightly] guided. (2:157 ) How should we understand this? Is it something similar to those HE, HIS angels and the believers should send to our Prophet () as mentioned in (33:56 )?
