In this verse, the author refers to a new commandment that is both an old truth and a new revelation. This commandment is rooted in the teachings of Jesus, who embodies the ultimate expression of love and truth. The darkness represents the absence of God's presence and the ignorance of His ways, while the true light symbolizes Jesus, who illuminates the path to righteousness and understanding.
The phrase "darkness is passing" suggests a transformative process where the old ways of sin and ignorance are being replaced by the new reality of living in Christ's light. This transformation is evident in the lives of believers who reflect the love and truth of Jesus. The true light is not just a future hope but a present reality, already shining and influencing the world through the actions and lives of those who follow Christ.
This message calls Christians to recognize the presence of Christ's light in their lives and to actively live out this new commandment by loving others and walking in truth. It is a call to be agents of change, reflecting the light of Christ in a world that is still emerging from darkness.
