What do you think about? What we do reveals how we think. The command that Paul has been stressing in Philippians 4 is to "rejoice always" and within that command he tells us that we should "not be anxious about anything" but rather "pray about everything" and to "think on these things" What things? We are given 8 things that we are to be renewing our minds on in Philippians 4:8-9.
