I have been to the eye doctor many times. Sometimes they would dilate my eyes and everything would get so blurry and out of focus. It would be hours before I could really get my focus back and see clearly.
Sometimes things were blurry not because my eyes were dilated but because my eyesight wasn’t what it should have been and I needed glasses.
Some Christians are going through life and their spiritual eyes are either dilated. their focus is off. Things are blurry. Jesus reminds us in Matthew 6:1-34 that we need to make sure our spiritual vision is clear and that we are focusing on the right things.
