Joseph said : Gen 50:20 You intended to harm me, but God intended it for Good, to accomplish what is now being done. The truth of God's word is embedded in these very words. God works all things for good of those who love him. God may allow bad days and suffering because of the evil actions of fellow humans, even though he can supersede such deeds so as to work out his will.
Heart be steadfast, secure trusting in the Lord in the end you will Triumph.
