Be of the same mind one toward another.
As believers, we really have no excuse for not agreeing with each other. God tells us in the Bible that we all have the mind of Christ. We may not understand every issue, but what we do know should bring us together. Unfortunately, we have many people who refer to themselves as Christians who purposefully choose to not agree with other Christians. Sometimes, it is necessary to stand on the word of God alone, but we must be very careful to make sure that we don’t stand on our own opinions about the Bible rather than what it really says.
If we really want to get along with each other, we need to start by getting our minds in line with Jesus. We can’t “live in harmony” and leave our minds out of the picture. That is not a healthy way to live. God expects us to live with our minds fully involved as we read about in Romans 8. If our minds are involved, then to live in harmony means that we need to work out what we think so that we can be in agreement.
I understand that there are those who refuse to stop arguing even though they can’t produce a good reason for their thinking. I believe that in this case, the best we can do is to keep praying for them and hope for another opportunity to find agreement while watching ourselves to make sure that we are not the ones who are wrong. This verse reminds me how important it is for us to bring our reasoning together in Church and not think that just because we meet together that we are united as God expects. We are a single body and Jesus is the head. When we disagree, someone is not getting their thoughts in line with Jesus’ thoughts.
