When studying a passage, I enjoy reading commentaries, word studies, and other research materials. Yet, I’ve learned to also consult Christians who lived closer to the time of Jesus than the scholars and commentators who give us great work. Neither the early church leaders nor modern scholars are always right, but it doesn’t mean they didn’t get anything right.
Some good neighbors instruct a person to be saved using Romans 10:9–13, and they even use this passage and say, “Invite Jesus into your heart,” or, “Pray the sinner’s prayer.” Allow me to say that I don’t question a person’s sincerity in their beliefs. As the late Antonin Scalia once said, “I attack ideas. I don’t attack people. Some very good people have some very bad ideas.” Neither the sinner’s prayer nor asking Jesus into your heart is in the Bible. This notion can be traced back to Billy Graham popularizing it in his crusades.
Historian Thomas Kidd traces it back to Anglo-American Puritans in the seventeenth and eighteenth centuries. The Puritan devotional writer John Flavel spoke of those who heard the gospel but would “receive not Christ into their hearts.” Thomas Boston, a Scottish Calvinist, encouraged Christians to take communion to receive “Christ into their hearts.” Benjamin Colman wrote in the early eighteenth century that Christians should “receive Christ into their hearts and hold him forth in their lives.” The phraseology became more and more formalized as time passed.
How should this passage be interpreted? Let’s ask some ancient Christians. While many have commentaries on this passage, I want to introduce you to Augustine. Augustine lived from the middle of the fourth century into the fifth century. He was a rather worldly fellow until he heard the preaching of Ambrose of Milan. Ambrose communicated the gospel in a way that appealed to Augustine because the sinner was also a philosopher and very intelligent. Most of the preachers he heard preached so simply that it turned him away, but Ambrose helped him. Later on, Augustine would become the bishop of Hippo (now Algeria). Western civilization owes a lot to Augustine. He lived to see the fall of the Roman Empire, and his writings have shaped much of Western civilization.
In his writing entitled The Christian Life, Augustine writes, “This condition is fulfilled at the time of baptism when faith and profession of faith are all that is demanded for one to be baptized.” Just as we do today, we ask for their confession before baptizing someone. They confess that they believe that Jesus is the Son of God. We also see it in verses such as Acts 2:21, 9:14, 22:16, and 1 Corinthians 1:2 in one form or another.
