In this psalm, David first petitions God to restore him to his homeland, so he may continually partake in acts of worship, both inwardly and outwardly (vv. 4 and 6). Secondly, he implores for divine protection and preservation from all affliction (vv. 7 and 12). Ultimately, he expresses his expectation that with such a divine protector as God, he not only anticipates earthly blessings but also eternal joy in heaven, encouraging others to share in this hopeful vision (vv. 13 and 14).
The Lord is my light and my salvation; whom shall I fear? Adversity brings darkness, while prosperity brings illumination. Tribulation can unsettle and confuse the soul, obscuring clarity of action, leading either to impatience or other sins. Yet when the Lord dispels the darkness with heavenly light, the soul perceives that the sorrow, which instilled fear in the night, is but a shadow. Under God's guardianship, not only does this fear hold no power, but it also yields remarkable blessings. Acknowledging this grace, David sings, The Lord is my light and my salvation; whom shall I fear? This can be understood as: ignorance and frailty have made me anxious during trials; however, when the Lord illuminated my understanding and revealed that temporary hardships are neither perpetual nor severe, and when He restored my health with the balm of His grace, I ceased to fear anyone. The Lord is the fortress of my life; whom shall I dread? He bolsters his assurance by affirming that no fear should overtake him. For the Lord, he states, not only provides illumination and healing but also does not abandon those He enlightens and heals, continually enveloping them with the shield of His divine provision and goodwill. Of whom shall I be afraid? If God is for us, who can stand against us (Rom. 8:31)? And if a king, safeguarded by an army of mortal soldiers, is unafraid, can the servant of the Almighty shielded by the eternal Lord’s protection be afraid?
