Fair is, in many ways, lukewarm. Fair will never die for another, will never extend itself for another, will never challenge another to greater heights. Fair is a judgment you make that is predicated upon your chosen perspective. Fair denies, or, at the very least, ignores, God’s perspective. Fair is in many ways opposed to faith.
It’s not fair is the wound that was exposed and exploited in the Garden of Eden. Satan’s promptings were given a place to resonate in the hearts of Adam and Eve when they doubted God’s providence and said to themselves. “Well, that doesn't seem fair.”
Fair is fear of God’s will. “It’s not fair” is the battle cry of those who are not willing to acknowledge with their whole heart, mind, body and soul that God is God and He is their God. Ultimately, your response to life falls into one of two categories, Job’s wife or Job’s. The choice is “curse God and die” or “The Lord give and the Lord take away. Blessed be the name of the Lord.”
“It’s not fair” means your heart is not ready. It is time for it to be ready. Prepare your heart by trusting in God grace and mercy. His will, though perhaps not earthly fair, is heavenly perfect.
