Children tend to fall ill more often than adults. This is because adults have stronger immune systems—having already fought and overcome many illnesses on their way to maturity.
The same principle applies to life itself. Some people collapse helplessly when faced with trials, while others remain unshaken no matter what hardships come their way.
Those who have never faced difficulties, or who repeatedly give up when they do, often have weak “life immunity” and struggle more easily. In contrast, those who have endured many hardships—or who keep striving to overcome them—develop a stronger resilience, enabling them to withstand even greater challenges.
In the end, trials are not obstacles to avoid, but essential experiences that strengthen the immunity of our lives.
