You may wonder if God even cares about you, but he does, and the proof is that he sent his son into the world to purchase your salvation. When we give our lives to Christ, God makes us his children forever.
Ask God to lead you as you seek employment. Be open to whatever he has for you — even retraining for another job. Don’t be a defeatist, but see your age and your experience as potential assets. Wise employers know that older workers often are the most dependable and responsible.
In the meantime, ask God to fill your days with useful activities. Can your church or other agencies in your community use you as a volunteer? Does your church have a Bible study for people your age?
