This book is a study of contrasts between visible things of Earth and invisible things of the kingdom of God. The Scriptures tell us, "Do not love the world or anything in the world. If anyone loves the world, love for the Father is not in them. For everything in the world--the lust of the flesh, the lust of the eyes, and the pride of life--comes not from the Father but from the world. The world and its desires pass away, but whoever does the will of God lives forever."
I John 2:15-17 NIV
The Bible also tells us, "Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is--his good, pleasing and perfect will."
Romans 12:2 NIV.
Why not make a decision to "Set your minds on things above, not on earthly things"

John 3:3 NIV.
