"For you were once darkness, but now you are light in the Lord. Walk as children of light." Ephesians 5:8

What does Scripture tell us of this spiritual darkness that we once were?
Jesus speaking of Christ (Himself being Jesus the Christ) in John 1:4-5, "In Him was Life, and the Life was the Light of men. And the Light shines on in darkness, for the darkness has never overpowered it [put it out or absorbed it or appropriated it, and is unreceptive to it.] The Amplified Bible

John 3:19-20 tells us,
"And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed."

But God, Who is love, by His mercy and grace saved us!

"For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish...for God did not send His Son into the world to condemn the world, but that the world through Him might be saved.
He who believes in Him is not condemned; but he who does not believe is condemned already..." John 3:16-18

Even the faith to believe is God's gift, "For by grace you have been saved through faith, and that not of yourselves, it is the gift of God." Ephesians 2:8

"For it is the God who commanded light to shine out of darkness who has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ." 2 Corinthians 4:6

No longer darkness, but children of Light, so we are to walk as such!
"And have no fellowship with unfruitful works of darkness, but rather expose them." Ephesians 5:11

"See then that you walk circumspectly, not as fools but as wise, redeeming the time, because the days are evil." Ephesians 5:15

How then is the walk of the children of light? We walk-- In newness of life:
"Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life." Romans 6:4

By faith:
"For we walk by faith not by sight." 2 Corinthians 5:7

In love:
"And we walk in love, as Christ also has loved us and given Himself for us, an offering and a sacrifice to God for a sweet smelling aroma."
Ephesians 5:2

In Christlikeness:
"He who says he abides in Him ought himself also to walk just as He walked."
1 John 2:6

In the Spirit:
"I say then: Walk in the Spirit, and you shall not fulfill the lust of the flesh. For the flesh lusts against the Spirit, and the Spirit against the flesh..."  Galatians 5:16-17

This being so, let us gather in the fruit of the Spirit, "But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self control. Against such there is no law."  Galatians 22-23 So then, "If we live in the Spirit, let us also walk in the Spirit." Vs. 25

In our liberty in Christ, let us therefore, "Standfast therefore in the liberty by which Christ has made us free, and do not be entangled again with a yoke of bondage." Galatians 5:1

Thank you most holy gracious Father for this life which is the Light (Christ
Jesus) for all who believe. As we enter into this season of preparation for Easter, increase our understanding of how priceless this gift of salvation is to us and how costly is was for You. With grateful hearts we worship You most holy and mighty God. Amen
