If God is good, and knowing everything, then he must know what it is like to sin, but if he know's what its like to sin he can't be all good, how can a person of faith answer this one?

​    Hello this is an interesting question ah that God has sinned, clearly then the person is not God. This is to depend on if you are asking if God is in human form? Of course, the only way would be to become God at a later time. God is not human and if there is an error or sin then that is not God. Will God reside in the flesh? Yes, at Revelation 12: 1–2 and also at Revelation 21:3.
