There are still many dark sides to ourselves.

"Beloved:  Now this is the message that we have heard from him and proclaim to you: God is light, and in him there is no darkness at all."  (1 John 1: 5 RM).

God is absolute light in whom there is no shadow of darkness.  But we Christians are not light. There are still many dark sides to ourselves.
Therefore, we need discernment of spirits to help us know when the good spirit is at work in us and when the dark spirit is in control. Whatever brings fear, worry or doubt in you is not from the Father of Light.

"Now the works of the flesh are obvious: immorality, impurity, licentiousness,  idolatry, sorcery, hatreds, rivalry, jealousy, outbursts of fury, acts of selfishness, dissensions, factions,  occasions of envy, drinking bouts, orgies, and the like."  (Galatians 5: 19 - 21).

The spirit that causes such behaviors as above causes sadness, depression, fear, worry and doubts.

"In contrast, the fruit of the Spirit is love, joy, peace, patience, kindness, generosity, faithfulness, gentleness, self-control. Against such there is no law."  (Galatians 5: 22 - 23).

Beloved, learn to discern the spirit at work in you in all things, always and everywhere.

"Almighty God, your incarnate Word fills us with the new light he brought to men. Let the light of faith in our hearts shine through all that we do and say. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever. Amen." (Prayer, Vespers Thursday in the Octave of Christmas).
