I am currently studying the book of Romans in my personal time with the Lord. One of the recurring themes I have continued to find is the connection between our thoughts and sinful actions. Over and over again, I am seeing that the battle for sin begins in the mind. When our minds are centered on the Gospel, there is life and peace and the ability to obey God's law. However, when our minds are focused on ourselves and on worldly things, we are living in the flesh and unable to please God. Setting our minds "on the things of the Spirit" begins with thinking rightly about who God is and agreeing with what God says about us.
Today, may we take our thoughts captive in obedience to Christ (2 Corinthians 10:5) and focus our minds on Gospel truths. May we "put to death the deeds of the body" (Romans 8:13) by walking according to the Spirit.
