There seems to be a growing number of people who believe that the God of the Old Testament is not the same God of the New Testament. This belief is not exactly new or revolutionary. It really has been around for centuries, ever since Marcion spouted ideas like this and got excommunicated from the church for being a heretic in the year 144 A.D. But as the years pass by, we are seeing more and more professing believers agree with this sentiment—that the loving and lovable Jesus who arrived on earth in the first century A.D. is not the same God as the fiery and vengeful One of old.
In Ligonier Ministries’ biennial State of Theology survey, they asked both believers and unbelievers whether they believed that “God learns and adapts to different situations.” Forty-eight percent of professing Evangelicals who participated in the survey agreed with this statement.[1] This means that about half of supposedly Bible-believing Christians in this country believe that God is able to and does change over time.
However, this belief is not a biblical one, and as we’ll see in a moment, how we think about this issue has a great impact on our Christian faith.
