The video of this post is by Pastor Sinclair Ferguson. In 5 minutes, he explains the unity of the Old and New Testaments by means of speaking of the covenants God made with men. In the process, he explained that since the fall, salvation has only been by grace. In other words, people who say, “Old Testament salvation is by law and the New Testament salvation is by grace,” seriously err. [That is, teachings like Dispensationalism, developed in the 19th century, are wrong when they propound two ways of salvation; and religions that believe they can earn their way to God, to heaven… are also wrong.]
