Summary: To accept one another, we are to think of God’s judgment.
Someone wrote, “Everyone has the fingerprint of God on his or her soul. God has created each person, knows him or her inside out. God has created each person and has plans and dreams for each one. God has created each person and so each one has incredible value. When we realize this, it changes how we see and treat each other. Accept one another. See them for who God has made them to be. There is a place for everyone in our church. God does not turn anyone away. He accepts all who come to him. How can we ever turn anyone away?”
First, we are to ACCEPT one another in Christ. Romans 15:7 (quickview)  command us, “Accept one another, then, just as Christ accepted you, in order to bring praise to God.”  To accept means “to receive wholeheartedly, to warmly welcome them to yourself, to grant admission into your heart, to look beyond anything superficial and to be willing and open to build relationships.” God accepting us in Christ is the basis for our accepting one another.
Romans 14:1 (quickview)  command us, “Accept him whose faith is weak, without passing judgment on disputable matters.” Note that there are disputable or non-essential matters and there are essential matters of the faith. Thus, we are to CONCENTRATE on the essentials. Truth divides as well as unites. Unity is based on truth. We don’t unite at the expense of the truth.
But we also need to CONCEDE differences. There will be some gray areas or “disputable matters” that we will never agree upon on this side of heaven. These are matters that are not worth fighting over. But it is worth accepting one another.
Romans 14:19 (quickview)  tell us, “So then we pursue the things which make for peace and the building up of one another.” Instead of wasting time debating about our differences, we must EXERT efforts to edify or build up one another.
Not all judging is wrong. One of the verses of the Bible that is most often quoted out of context is Matthew 7:1 (quickview) . “Do not judge, or you too will be judged.” But Jesus is not prohibiting judgment per se. What He was commanding was premature judgment. Look at verses 4-5: “How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.” Before we judge others, we must first judge ourselves.
What is the judging that God prohibits? Now, note that “therefore” in verse 13: “Therefore let us stop passing judgment on one another.” Why is that “therefore” there? This is a conclusion of a previous argument. Let us read Romans 14:9-12 (quickview) . “For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living. You, then, why do you judge your brother? Or why do you look down on your brother? For we will all stand before God’s judgment seat. It is written: “‘As surely as I live,’ says the Lord, ‘every knee will bow before me; every tongue will confess to God.’” So then, each of us will give an account of himself to God.”
