Have things happened to you that were discouraging and unexplainable? That probably includes most of us. You could cry out to God, "Lord, why?" The answer is certain. God is working to bring good out of all things for his glory.
God does all things to bring glory to himself through Christ our Lord. When bad things happen to you, pray that God will bring good out of it to his glory. The reason for all things is the glory of God.
Only God sees the end from the beginning. His providence rules over all. He never causes evil. God is always good. He works through bad things to bring good out of it. The greatest example is the cross of Christ. Evil men demanded his crucifixion. Three days later, God's goodness and glory prevailed.
"For of Him and through Him and to Him are all things,
to whom be glory forever."
Romans 11:36
"And we know that all things work together for good
to those who love God, to those who are the called
according to His purpose."
Romans 8:28
