Malachi 3:14 and 17

The people of Isreal said " we didn't get anything out of following God, and our enemies still seem to be prospering, so why should we follow him?" Then later, God says "They (his followers) will be mine... my treasured possesion!!!" (I added the exclamation marks). My motivation to follow God needs to be this: so I can be in the care of a God who calls me his treasured possesion. to be treasured. Not just to gain stuff or status. To belong exclusively to the most powerful being in the universe. To have his smile, his approval, and his everlasting love.
Es muy chevere, no? Que bueno.
