Grey is the absence of color, although grey is often called a color. In black and white photography there are shades of grey. A grey scale shows shades of grey from black to white. Spiritually there is a right and a wrong, truth and lies, good or evil. These are opposites as is black the opposite of white. Most live in the murky grey of compromise. When I rededicated my life to the Lord I was in a church that taught that there is good and evil and that we are not to mix them up. Without Jesus we would be lost in the murky grey of sin.
Rom 3:19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
Rom 3:20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
Rom 3:21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
Rom 3:22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
Rom 3:23 For all have sinned, and come short of the glory of God;
Rom 3:24 Being justified freely by his grace through the redemption that is in Christ Jesus:
Randy the wounded goose stands before the grey of the pond. The pond is grey because the sky is grey. He watches the ripples caused by a gentle wind. The Greek word for spirit is pneumos, meaning wind.
John 3:7 Marvel not that I said unto thee, Ye must be born again.
John 3:8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
We have a blue Jay called the Scrub Jay. It has blue feathers and a grey breast. A bluish grey is called a cool grey. Grey with hints of tan are called warm greys. The Lord has made good use of colors. Most any color goes with grey. Grey or gray is the same word. The KJV Bible uses the spelling "gray". Old people have gray hair.
Pro 20:29 The glory of young men is their strength: and the beauty of old men is the gray head.
The Robin has a grey top and a red breast. He is a warm grey color. My hair used to be a reddish brown, but I noticed a few years back that the barber started putting gray hair on the floor. Was he getting it from a bag just to trick me? We will all get gray if we live long enough. I am still young in spirit. Jesus keeps us young.
