“… all… come short of the glory of God”

Wrong Interpretation:

Christians who embrace imperfection often recite this cut-off, scriptural reference to reinforce that sinning is inevitable and inescapable.  Therefore, we are all sinners so– judge not.

Right Interpretation:

The correct scripture actually says this in the past tense,

For all have sinned, and come short of the glory of God; ~Romans 3:23 KJV

This scriptural passage is referencing that every man needs the Savior Jesus Christ to become righteous. No man can claim righteousness by the deeds of the law, which Paul was referring to the circumcision of the flesh. The law on tablets revealed that all men were guilty, but faith in Christ cleanses them. Paul tells us that this does not mean we do away with the law, but we establish it. Christ is the completion of the law.  Christ makes us saints who “punish all disobedience when our obedience is fulfilled.”

So, when the imperfect Christian takes this scripture out-of-context, correct them because it should never be used as an excuse to be inadequate, imperfect, or a sinner in Christ.
