When a young child in a Reformed church desires baptism, you can have more confidence it is prompted by the Holy Spirit than in any other type of church. The main reason is because of the Reformed tradition’s emphasis on the right preaching of the gospel every Sunday.
I have heard so many testimonies of people who got baptized early in life, but when they got older they finally understood the gospel, and then got baptized for real. Because of that common “testimony,” it causes many good Christians to be hesitant to encourage their child if their child desires baptism.
But there’s a huge difference between a child in a Reformed church desiring baptism versus a child in a broadly, evangelical church desiring baptism. That main difference is the gospel!!! It is totally possible to go to church for years in America, and never hear the gospel.
I’m in the middle of a Facebook debate with a few people about the need to trumpet the doctrine of sin. And these are professing Christians! If there are professing Christians who do not think the doctrine of sin is that important, you can be sure the gospel is not that clear to many professing Christians.
But it is so different in a Reformed church! Every sermon, every prayer, every song, every Communion– it’s all gospel-centered! Especially in preaching- every sermon in a Reformed church is supposed to show man how they have broken God’s Law, and how Jesus Christ solves that problem in His saving work. Every sermon is somehow showing how Jesus has fulfilled some promise of God to His people. Every sermon, children are hearing how Jesus is the only way to salvation. Every sermon they are being told “you are a sinner– here’s how you have sinned. Here’s what you deserve for that. But now here is who Jesus is. Here is what He has done! And now, repent and be baptized in response to that. Do you believe? Then repent and be baptized.”
They hear that in some way, shape, or form week by week, month by month. They see a minister of the gospel up front give that message, they hear the pleas, they can see the urgency in his face. On top of that, we know that preaching is precisely what the Holy Spirit uses to save (Romans 10.13-17)! Is it any wonder that a child hearing Reformed preaching on a regular basis will desire baptism?
