“The eye is the lamp [light] of the body; so if your eye is clear [spiritually perceptive], your whole body will be full of light [benefiting from God’s precepts (laws, commands)]." Matthew 6:22
If we think about the eyes literally, they are the primary way light enters our body (clearly, it also enters through our skin since it is the body's largest organ). But, light enters the pupil, and the iris controls how much light enters. Then, it passes through a lens, which works with the cornea to focus the images we are seeing. The light then passes through the retina, and literally kickstarts an electrical process that sends signals to our brain to show us the images.
I found that completely fascinating and amazing, a miracle of creation, something only God could do. Praise God! Like the rising of the sun in the east, and setting in the west. Hallelujah!
Now, the good news of salvation is everlasting life through Jesus Christ as our Lord and Savior: "That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved." Romans 10:9
If we believe this, even though our flesh is weak, we have been set apart as holy for God:
"And in accordance with this will [of God] we [who believe in the message of salvation] have been sanctified [that is, set apart as holy for God and His purposes] through the offering of the body of Jesus Christ once for all." Hebrews 10:10
Likewise, if we think about it spiritually, as in Matthew 6:22 (above), if our eye is clear '[spiritually perceptive],' or focused on God, what is right, good and pure, we will never again be in darkness, regardless of the infirmities of the flesh, because Jesus tells us, we are the light of the world. Matthew 5:14
So, with our physical eyes, we SEE the lights of the world,
but with our spiritual eye, we ARE the light of the world,
and will never again be in darkness.
Or, as Apostle Paul told, in the story of 'A Thorn in the Flesh':
2 Corinthians 12
A Thorn in the Flesh
7 "Because of the surpassing greatness and extraordinary nature of the revelations [which I received from God], for this reason, to keep me from thinking of myself as important, a thorn in the flesh was given to me, a messenger of Satan, to torment and harass me—to keep me from exalting myself!
8 Concerning this I pleaded with the Lord three times that it might leave me;
9 but He has said to me, 'My grace is sufficient for you [My lovingkindness and My mercy are more than enough—always available—regardless of the situation]; for [My] power is being perfected [and is completed and shows itself most effectively] in [your] weakness.' Therefore, I will all the more gladly boast in my weaknesses, so that the power of Christ [may completely enfold me and] may dwell in me.
10 So I am well pleased with weaknesses, with insults, with distresses, with persecutions, and with difficulties, for the sake of Christ; for when I am weak [in human strength], then I am strong [truly able, truly powerful, truly drawing from God’s strength]."
Let your light so shine before men, that they may see your good works, and glorify our Father which is in heaven. Matthew 5:16
Faithful and humble servant of our Lord and Savior, Jesus Christ.
