"The eyes of your spirit allow revelation-light to enter into your being. When your heart is open the light floods in. But when your heart is hard and closed, the light cannot penetrate and darkness takes its place." From the Passion Translation.
"The eye is like a lamp to your body." The literal Greek text reads, "Your eye is the lamp of your body. If your eye is healthy, your whole body is full of light; but if it is sick, your body is full of darkness." The eye becomes a metaphor for spiritual perception. The body is our spirit. The lamp is Jesus' teachings. The darkness is formed by the lies and opinions that blind us. These metaphors have been made explicit." The Passion Translation.
The idiom "if looks could kill, I'd be dead right now" is used to remark on an obviously disgusted, disapproving, or angry look from someone. So what a blessing it is to make eye contact with a stranger and they smile warmly back at you. In my early days when I first met Jesus, the old timers would say, "That person has got Holy Ghost eyes." Also back then we used to sing a song called This Little Light of Mine.
When I was a little girl I remember my dad saying, "When you meet someone look them straight in the eye and give them a firm handshake." As I got older I would often go home to take care of my parent's business. Sometimes there were problems with the delivery men bringing orders. I'd ring my dad and tell him, "They know you are away and I'm just the boss's daughter." He'd say just to look them in the eyes and let them know you mean it.
There are times I haven't been able to look at people for fear of rejection. But the Lord said to me, "Don't do that, because when the evil spirits see fear they are like sharks with blood in the water, they hone in on it." Faith is the opposite to fear.
"So don't hide your light! Let it shine brightly before others, so that your commendable works will shine as light upon them, and then they will give their praise to your Father in heaven." Matthew 5:16.
