Malachi 2:14; Malachi 2:17
You ask, "Why?" It is because the Lord sees how you treated the wife you married when you were young. You broke your promise to her, even though she was your partner and you had an agreement with her.
You have tired the Lord with your words. You ask, "How have we tired him?" You did it by saying, "The Lord thinks anyone who does evil is good, and he is pleased with them." Or you asked, "Where is the God who is fair?"
