Having established that the Christian brother with the more sensitive conscience is not to condemn the brother with more liberty, Paul expands on this instruction with a rebuke and a warning for those who do condemn their fellow Christians.
“Who are you to condemn someone else’s servants? Their own master will judge whether they stand or fall. And, with the Lord’s help, they will stand and receive His approval. ” Romans 14:4 NLT
In no uncertain terms, Paul establishes that my brother is accountable directly to God, not to me. My conscience is not the standard by which he is to be judged; and, if I condemn him based on my own convictions, I am completely out of order, in a place I have no business being. The judgment of my brother belongs solely to God.
Not only is my brother’s judgment in God’s hands, however, but also God has every intention and the complete power to enable him to stand perfect and righteous, a completely successful servant, at the last day. God doesn’t even need my help to bring this about!
By all means pray for your brother; we are told multiple times in the New Testament to pray for one another. But leave him in God’s completely capable hands to transform him into the image of Jesus Christ. In the meantime, accept him as one for whom Christ died, one whom Christ loves dearly.
