Let me guess, you believe Ancient Israel was populated by brownoids, and it was all deserts and shrubs

Matthew 6:20-23
"But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: For where your treasure is, there will your heart be also. The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!"

Where you lay your treasure your heart will be also. If your eye sees light, you will be full of light, and if you see darkness, you will be full of darkness. Today the world is filled with degeneracy, ugly buildings, individuals, and beliefs. Hence why so many picture the literal promised land to be desolate rather than lush and beautiful
