I Corinthians 1: ⁸ He will also strengthen you to the end, so that you will be blameless in the day of our Lord Jesus Christ. source

You have this promise.  All those in relationship with JESUS can rest on the promise that He will strengthen you for as long as you are on this planet. Now that is a huge and wonderful and great and exciting and reassuring promise; but that is not the only promise in this verse. 

Blameless

Isn’t that a superb word? In Greek it’s anemkletos.
I think you will be pleased to see this Greek word means: cannot be called into account; unreproveable; unaccused.  source 

So this means as used in context all people in relationship with JESUS will on a day certain stand person to person in His Presence and on that day we will be blameless!
Yes! Blameless!
Not one sin will be held against us.
Now if you see this as a license to sin; if you see this as a get out of jail free card; or a means to live a licentious lifestyle, then I urge you to check your profession of faith. You will likely find you are not in relationship with the CHRIST. 

But for those who have truly confessed their need of a Savior, have believed and received His Blood Atonement, we in the Presence of the HOLY GOD of CREATION! cannot be called into account; (we are) unreproveable; (we are) unaccused. 

Again and again the Evil One accuses us now but the day is coming he will be shut-mouthed forever! Glory Hallelujah! 

So are you ready to Selah today?
