It is true that many times we live under the shadow of the Old Testament. In the Old Testament we see a group of laws to fulfill, of people judging by everything you do, but in the New Testament we see a waste of mercy and love. The New Testament presents the church as a community of people who feel great brotherly love for one another, this means that if our churches are not expressing that love, then they are not communicating to the world the true biblical community that represents the love of Jesus.
The Old Testament mentions expressions in the law of Moses such as: “An eye for an eye, a tooth for a tooth”. Instead, the New Testament commands us to love our enemies. I believe that a part of the church today prefers an “eye for an eye” or to judge the brother and trample him.
