“And we know that in all things God works for the good of those who love Him, who have been called according to His purpose” (Romans 8:28 NIV).
Are you a child of God? If you are, then you’ve been called according to His purpose, and therefore, the above promise is for you, and it covers all your circumstances, as expressed in—“All things.” What is the promise? The promise is this, none of your experiences (good, bad, painful, intentional, unintentional, engineered by the devil, by people, etc.) are ever wasted. God in His infinite wisdom uses them all to bring about something good in your life, and needless to say, to bring Him glory! He gets glory, because you will praise Him, and testify to His love, wisdom, and faithfulness.
Let us consider Joseph, son of Jacob. His brothers sold him into slavery into Egypt. He ended up in jail after being falsely accused by his master’s wife. He was forgotten by those who could have helped free him, but God worked it out. In the end, he became the vice to the Pharaoh (Genesis 41:41-44 NIV), and through him, God provided for everybody, including his own family (his father Jacob and his mean brothers and their families) during the seven years of terrible famine.
After the death of Jacob, the brothers were afraid of retaliation from Joseph, but to reassure them, he said to them, “You intended to harm me, but God intended it for good to accomplish what is now being done, the savings of many lives” (Genesis 50:20 NIV).
So take heart, my brother, my sister; your pain and suffering are not for naught. As you are a child of God, He will work it out for your good and for His glory! He said it, so believe it, because He is faithful!
