Olives
Let us remember.....We are an unusual bunch of Olives , some Green , some Black , some Purple , sweet, sour , salty , bitter - quite complex really. In general the darker the Olive the riper it is. We are all grafted into the Olive tree by Grace & Mercy through Jesus Christ our Lord & Savior.
Romans 11:23 NKJV
And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again.
Nice parallel . . .
