Light

Read through these verses for me:

• "This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all" - 1 John 1:5. 
• "But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light" - 1 Peter 2:9.
• "For you are all children of light, children of the day. We are not of the night or of the darkness" - 1 Thessalonians 5:5.
• "For at one time you were darkness, but now you are light in the Lord. Walk as children of light" - Ephesians 5:8.

Now read this one:

• "The light shines in the darkness, and the darkness has not overcome it" - John 1:5.

 If God is light, if we are called out of darkness into His marvelous light, if we are children of light, if we are light in the Lord, and if the darkness has not overcome the light (nor will it ever because the Light made the angelic powers that fell into darkness), how can it be said that we can lose our salvation?

It would be saying that darkness has overcome the light.

It would be saying that Satan has overcome God!

Can children of light walk as children of darkness?  Oh yes...and of course this grieves the Holy Spirit and blemishes our testimony.  We are commanded to walk as children of light.  This means we are to love the truth and conduct ourselves in holiness and purity.  Children of light however, will never be overcome by the darkness or be cast back into the domain of Satan once they are brought out of it into God's marvelous light!  Never, for God who is light has overcome darkness through Jesus Christ our Lord!

God Almighty cannot be overcome!
