Radiant Light

Darkness, fleeing at the approach of Promise,
Star bright and resplendent,
The Sun, illuminating the Virgin’s womb,
Making of it a palace
Fit for a king, a King of Kings.

Light bright angel,
Carrying her “Fiat” heavenward,
Enfolding humility, modesty and obedience,
In the gold of innocence and virtue.

Most High overshadowing,
Virgin most pure and lowly,
Conceiving by privilege,
Godhead and Son of Man.

The first and most obvious is the change in coloration of the Sun, as well as a severe drop in the Sun’s brightness. On an airless world like the Moon, the Sun at sunset would look no different than at any other time. But it’s the Earth’s atmosphere that makes sunsets so special.

When the Sun appears progressively lower and lower on the horizon, its light needs to pass through more and more of the atmosphere to reach our eyes. You might not think of the atmosphere as being a very good prism, but when you pass through around 1000 miles of it just before the Sun dips below the horizon, it starts to add up.

The bluer wavelengths of light get scattered away, leaving only the reddest wavelengths that reach your eye. As the sun drops towards the horizon, it progressively loses violets and blues, then greens and yellows, and finally even the oranges, leaving only the reds behind.

You may not even realize it, but by time you’d see a sunset like the picture above, the Sun has already technically set, it’s only due to the fact that the atmosphere bends light that we’re still seeing it like this.

This is why, if you time a sunset, it will take longer than the expected 120 seconds to go from the moment it touches the horizon to the moment it dips below, even during the equinox at the equator, where it rises and sets as close to completely vertical to the horizon as possible. The Sun appears to linger due to the refraction of our atmosphere.  READ MORE………

Be the Sun in Me

Be, O Lord, the Sun in me.
Despite, my clouds,
Masking Your Beauty,
Be seen as light invisible,
Going forth, in the Spirit,
To the world,
A world in need of Revelation.

Pierce the veil of my travail.
Linger long to suffer my malaise,
My unsettled wine.

By grace, bless me,
As you bless those
Blind to Your Presence in me.

Sacrament and penance,
My claim upon Your Heart.
Light, undiminished,
Under my bushel,
Burning bright within my core,
Make of me a lampstand,
In Your Father’s House.

Be, O, Lord,
The Sun in Me,
To a world in need of illumination.
