“Bloom where you’re planted” is a saying that holds great truth.
Firstly, it acknowledges that each of needs to be planted in a particular place. Way too many “Christians” either refuse to be planted, refuse to put their roots down, or choose where they will be planted.
Christians are not their own. They were bought with a price and the Husbandman [Jesus] holds the right to plant each one as He wills.
Once planted in the local church of His choosing, it is each individuals responsibility to become well rooted there in order to bloom and bear much fruit.
