Good luck?

Sometimes people wish good luck when someone goes for an exam or interview or some important assignment. Luck is understood as something that happens by chance and not by conscious efforts. When something goes wrong or mishaps happen people think that as bad luck.
David hounded for his national service of defeating Goliath. (I Samuel 17) Did luck desert him? Or his stars were not in right alignment? Defeat of Israelites in Ai was ill omen or bad luck? (Joshua 7) If luck and chance decide our lives, it is fate. Then there is no role for God or diligence or hard work or skills or knowledge.
1) Luck or God: People who believe in ‘luck’ leave God out of their perspective. They deny existence of a personal God.
2) Nothing is luck: Anything that happens by ‘chance’ is called ‘luck.’ If so, does it happen apart from God, without knowledge of God or God lost control? Sovereign God has absolute control over all creation. Even a hair does not fall without His knowledge, a bird does not fall without His will. (Luke 12:7; Matthew 10:29)
3) Lucky charms: There are few people who carry ‘lucky charms’ with them to ‘ward off evil.’ Sadly, the ‘charms’ do not have any power as such.
In all circumstances, introspection is needed. Instead of blaming others or circumstances or invisible luck, we must consider our ways. “Now this is what the LORD Almighty says: “Give careful thought to your ways. You have planted much, but harvested little. You eat, but never have enough. You drink, but never have your fill. You put on clothes, but are not warm. You earn wages, only to put them in a purse with holes in it.” This is what the LORD Almighty says: “Give careful thought to your ways.” (Haggai 1: 5-7) Let us examine our proximity with God, priorities, preferences and choices and repent to do God’s will.
Do I trust in God’s amazing plan?
