Being of one mind includes having compassion or sympathy for what the person is facing. We can be like-minded through the love Christ puts in our hearts and suffer along with others. Be courteous and humble about yourself.
Our Lord Jesus went into the slave market of sin, bought us, and took us out and set us free. So Paul could then write, “Stand fast therefore in the liberty where Christ hath made us free.” Ah yes, when He said it’s finished, God’s law was satisfied, God’s holiness was vindicated, and God’s redemptive purpose was fulfilled.
