The Christian life is a battle. Believers must be prepared to fight every battle that life brings and the Apostle Paul knows that many of life's battles are fought in the mind. Philippians 4:8-9 is a call for Christians to do battle in their minds. In these verses, Paul has given a list of virtues that Christians are to think on, which in turn will result in peace; the God of peace being with them. Furthermore, Paul instructs believers to practice what they have learned, received, heard and seen in him. In other words, Christians are to example Paul as he exampled Christ (1 Corinthians 11:1). Much of the experience of a Christian's life is a result of their thought life. Philippians 4:8-9 instructs us to think about all that is good in Jesus. This is the antidote to a lack of peace.
