 That water is a picture of the baptism ceremony. Like the time our Christian leaders put us under the water to baptise us. They didnt do that to wash the dirt off the outside of us. No. Its like that water washed the shame from inside us. When we asked those leaders to baptise us, we asked God to make us clean on the inside, so that we will not feel shame any more. So God saves us and gives us new life. Yes, we can have new life because, after Jesus died, he came back to life again.
