When you are in a toxic environment taking in toxic things, you often pollute your mind mentally and spiritually.  The same goes for when our hearts aren't in the right place in our walk with Christ.  

We can't attend church on Sunday's, worship praising and praying and leave it there when we leave.  We have to worship, praise and pray the other 6 days of the week. 

We talk about the importance of the environment of which your heart and mind are in.  Often times we forget that in order to continue growing in our relationship with God that we have to let go of our past and who we used to be.  We are made new!
