Arise and be baptized, and wash away your sins, calling on the name of the Lord. The most obvious thing that comes to mind when you see a person being put under water is the idea of washing. When we take a bath we are cleansing our body of dirt. When we are baptized it represents the washing away of sin. A little girl was watching her older brother being baptized.
Baptism represents complete washing away of sin.
But it is not the water that washes away sin. It is the blood of Jesus Christ which washes away sin. There are lots of great hymns that communicate this truth. Lay aside the garments that are stained with sin And be washed in the blood of the lamb. Nothing but the blood of Jesus.
