Are All Ten Commandments Taught in the New Testament?

Many professing believers in Christ believe that the Ten Commandments were abolished by the sacrifice of Jesus Christ on the cross. Some believe that Christ came to do away with those difficult commandments. Some others believe that He reinstituted only some of them. Some others assume that He replaced the Ten Commandments with a new commandment. Although these people may be sincere, they are deceived by the “god of this world” (2 Cor. 4:4; Rev. 12:9), who has used his false ministers to brainwash them with false doctrine (2 Cor. 11:13-15).
