Life constantly presents opposing forces, competing duties, and extreme situations. Navigating these successfully requires a delicate balance, ensuring one does not simply let go of one side to favor the other [מצודת ציון]. The primary approach among commentators is to view this as a call for moderation and the middle path. A person should not view themselves as entirely righteous or entirely wicked. Instead, they should live a balanced life, giving every part of their soul its proper place at the right time. This balanced approach also means avoiding the pursuit of matters that are beyond human understanding [תעלומות חכמה, אבן עזרא]. Ultimately, the person who fears God is the moderate one, able to safely avoid the dangers and pitfalls that wait for those who drift toward the extremes [ביאור שטיינזלץ].
On a psychological and emotional level, this balance applies to how a person reacts to life's difficult events. While it is appropriate to feel fear and let the heart tremble in the face of hardship, a person must also train their heart not to sink into excessive anxiety. A true fearer of God manages to satisfy both emotional needs. Someone who is too anxious shows a lack of trust in God, while someone who feels nothing at all ignores His guiding hand in the world [מצודת דוד].
Looking at this from a completely different angle, the need to grasp both sides also serves as a guide for absolute obedience to God and His prophets, even when a command seems to go against human moral logic. There are times when a righteous prophet might command an action that appears unjust or wicked. In such moments, a person is required to hold firmly to both their sense of justice and the seemingly wicked command without any doubt. The one who fears God fulfills both sides perfectly through unwavering obedience [רש"י, צאינה וראינה].
Finally, the necessity to hold onto different elements serves as a guide for studying God's laws. It recommends combining the study of the Written Law with the study of the Oral Law. A person who fears God is well-versed in both areas. This comprehensive knowledge equips them to stand firm in their faith and know exactly how to answer those who challenge it [תורה תמימה].
