The world considers this the chance happening of good or bad events apart from those controlled by the laws of nature. When God is not acknowledged as being vitally involved in the affairs of life, the tendency is to believe in
fate, a purely random, lucky or unlucky occurrence. God’s passive will allows

For a Christian everything has a God reason and purpose behind it

things to happen (as opposed to His active will, which causes things to take place) – even what evil people and Satan may propose for our harm. In all circumstances, for those who love God, these things work for good, as seen in the life of Job and Joseph (Job 1:8-12, 2:3-10, 42:10-17; Gen 50:20; Rom 8:28). In hindsight this will be our testimony too, as it was with Paul who stated, “What has happened to me has really served to advance the gospel” (Phil 1:12). We are under the covering of the blood of Christ and He is watching over even the smallest detail. God is sovereignly in control “Doing whatever pleases Him…Working out everything in conformity to His will” even when we do not understand why things are happening as they do (Ps 115:3; Isa 46:9,10; Eph 1:11).

Wouldn’t you rather believe what happens is planned by a loving heavenly Father (divine providence) and is not just a random chance or fluke? A so-called ‘lucky break’ is usually the result of action – exploring an opportunity or an opening which has been grasped. It is wise advice to prepare yourself and the opportunity will come, then thank God for it. Instead of saying, ‘Good luck’ to people, say ‘I trust it goes well for you’ or ‘I wish you well’ (or ‘may God bless you’ if appropriate).
