Is there such a thing as luck?

No, there is only the sovereign providence of the living and personal God.

How often do you here people attribute the source of avoided accidents, healing, blessing, or other prosperous occurrences to luck? On the flip side how often do you hear "bad things" attributed to being unlucky? Perhaps even as a professing Christian you may say things like, "Man, he is lucky" or "It is not my lucky day".

Is this thinking biblical?

The Bible presents a God who is absolutely sovereign over all of the affairs of the world Psalm 115:3…3 Our God is in the heavens, and he does as he wishes.…He is in complete control and he has ordained all things to come to pass. There is absolutely nothing that escapes his notice. He is not only sovereign over your salvation (Eph. 1) but he also is sovereign bird feeder …Matthew 6:26…26 Look at the birds. They don't plant or harvest or store food in barns, for your heavenly Father feeds them. And aren't you far more valuable to him than they are?…He is sovereign over the weather, whether 'good' or 'bad' …Matthew 5.45…45 In that way, you will be acting as true children of your Father in heaven. For he gives his sunlight to both the evil and the good, and he sends rain on the just and the unjust alike. Job 38:34-35…34 "Can you shout to the clouds and make it rain?…35 Can you make lightning appear and cause it to strike as you direct?.…For we even learn in Scripture that God is sovereign over the outcome of a role of the dice…Proverbs 16.33…33 We may throw the dice, (Hebrew We may cast lots.) but the Lord determines how they fall…There is nothing that comes to pass by chance, but rather all things come to pass through the sovereign providence of God.

I am not trying to be nit-picky here. But I do want to challenge you if you talk like a pagan and deny God of his glory through divine intervention. Think about it. How dreadful is it ifwe say that we've receive God's blessed artwork –creation by chance, which God works together for his glory, and we turn around and smudge out God's name from the authorship only to inscribe the vague, impersonal and fictional name "luck" at the bottom right corner of the artwork?… Since God does all things for his glory and causes all things to work together for good for those who love him, how dare we insult God through our careless speech?! …Romans 8.28…28 And we know that God causes everything to work together[a] for the good of those who love God and are called according to his purpose for them.

Let's use this as an exhortation to recognize and ascribe the personal hand of God to our understanding of the universe and all things in it. Let's delete the words fate, luck, by accident, and the like from our vocabulary and use words that reflect truth such as providence, sovereignty and God. …In this understanding and application of the doctrine of divine providence we will no doubt become keenly attuned to the work of God in and around our lives and more inclined to give him praise for his good providence.
