"The wicked man flees although no one pursues him; but the righteous man, like a lion feels sure of himself" (Proverbs 28:1).
Wicked men are even afraid of shadows; to them shadows of trees seem as an army. Wherever something rustles, the wicked man thinks; the avenger comes! The trembling of leaves, he hears as a sound of chains; he takes the voices of birds as the shout of hunters who give chase after game; he sees grass as a spy of his evil deed; water, as a witness against him; the sun, as a judge; the stars, as those who taunt him. O my brethren, how many lies are born out of fear? For fear is of sin, sin is of the devil and the devil is the father of all lies.
Fear is the first-fruit of sin. When Adam sinned, he hid from the face of God. And when God cried out, Adam said: "I heard your voice in the garden and I was afraid" (Genesis 3:10). Before sin, Adam did not know about fear; neither did he hide from the face of God but, on the contrary, always hurried to encounter God. And as soon as he sinned, he "was afraid."
"But the righteous man, like a lion feels sure of himself." Without sin, without fear. Without sin, without weakness. The sinless ones are powerful, very powerful and brave, very brave. The righteous ones are strong and fearless. Such are the righteous ones, only the righteous ones.
O Sinless Lord, save us from empty fear but before that, preserve us from sin, the parent of fear. To You be glory and thanks always. Amen.
