Why would you be delivered from something or someone and go back into Tue same mess,come and shake yourself loose from the shackles of darkness.
“He has delivered us from the power of darkness and conveyed us into the kingdom of the Son of His love, in whom we have redemption through His blood, the forgiveness of sins”.
{Colossians 1:13-14}
When we are transformed from darkness to light,our status changes,from nobody to somebody ,from outcast to royalty,and God says,

“But you are a chosen generation, a royal priesthood, a holy nation, His own special people, that you may proclaim the praises of Him who called you out of darkness into His marvelous light;As 1 Peter 2:9 tells us.
THEREFORE : As children of God.
“You are the light of the world. A city that is set on a hill cannot be hidden. Nor do they light a lamp and put it under a basket, but on a lamp stand, and it gives light to all who are in the house. Let your light so shine before men, that they may see your good works and glorify your Father in heaven.
[ Matthew 5:14-16 ]
