Be renewed!

Here is a good one by Einstein: "The significant problems we face cannot be solved at the same level of thinking which created them".

In other words, the current problems are created by the current thinking. Unless our thinking is renewed the same problems will remain.

... but be transformed by the renewing of the mind ... (Romans 12:2)

And that you be renewed in the spirit of your mind. (Ephesians 4:23)

Let this mind be in you, which was also in Christ Jesus, (Philippians 2:5)

For as the heavens are higher than the earth, so are My ways higher than your ways, and My thoughts than your thoughts. (Isaiah 55:9)
