God told the Ephesians that  if they repented, He would give them to eat of the tree of life.

He told Smyrna, that if they were faithful he would give them a crown of life.

He told Pergamos that if they repented, he would give them the hidden manna and a white stone.

He told Thyatira that if they held fast till he came, he would give them power over the nations and also the morning star.

God told Sardis that they thought their works were enough, but that they were dead.   (Sometimes we, too, just go through the motions. )  But those of the church who were faithful would "Walk with Me in white."

He told Philadelphia that they would become pillars in the temple, and that he would write upon them his new name.

He told the  Laodiceans that if they overcame, they would sit with him in his throne.

So.  Even though most of these churches didn't please God, he held out hope that if they would repent and obey Him, he would give them something.  None of them got the same thing.

The message is that even though you may not have pleased God in the past, there is hope for the future if you repent.  You get to start over.  God is merciful.

The symbolism in all the things God gave them is typical of the book of Revelation.   As I said a couple of days ago, it is a difficult book.  I certainly don't understand everything in it.
