What are you thinking? And, how does what you think determine how you live? 
We have several thoughts every single day, many of which have little to no major determining factors for our lives. What color socks you wear or which earrings you put on will not change the world order in your life. 
Scripture tells us to take every thought captive to the obedience of Christ! How we live out our faith in the world we live in does depend on how we think on the issues that matter. How the world defines value and how God does are becoming further and further apart. 
If our minds are set on the flesh it will lead to death or separation. The mindset on the Spirit is life and peace. We can either be conformed to the world in how we think or we can be transformed by the renewing of our mind and become more like Christ!

What you think about them and how you define them will determine how you live your life out and what will define your worldview. Write what you think about each one of them and then search the Scriptures to see how God has defined them, for His thoughts are not our thoughts and His ways are not our ways.
