change the voice man proposes God disposes​

Answer 1

man are proposed but god are disposed said by people

Answer 2

Answer:

God disposes those which are proposed by the man.

Or you can write it as God disposes those which man proposes.

The sentence is written in the active voice and you need to change it into passive voice.

In the case of active voice, the subject describes the predicate, and you need to change the voice to make a stress on the predicate of the sentences.
