Romans 14:12

So then each one of us must give an account of himself to God.

The Lordship of Jesus Christ, the inevitability of final judgment, the responsibility of every man to bear his own burden and give an account of himself to God, the certainty of every man's need of mercy at last, and the common tie of filial love within the redeemed community - these and a thousand other considerations should make an end of censorious judgments passed upon the strong and deprecatory judgments upon the weak, and deal a mortal blow upon the human conceit in which such judgments are invariably formed.

As Thomas said:

Earthly Christians are not lords to pass judgment upon their fellows; and, although Christians are to judge angels (1 Corinthians 6:3), that time has not yet come.[11]

With this verse, Paul ended one phase of teaching regarding weak brethren and strong brethren and passed to a consideration of the more comprehensive doctrine of Christian liberty and the proper exercise of it.
