Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? Therefore, we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in the newness of life. Romans 6:3-4 (NKJV)
As I understand what Paul writes here is that when a person is baptized, the sinful part of him or her dies. We were not only baptized into our death but into Jesus’ death as well.
We should walk in a new life because when God raised His Son, He raised Jesus into a new life by resurrecting Him and taking Jesus to live with Him. Because God did this for His Son, the Son will do it for us.
I wonder, do those who submit to baptism realize what it means to go through this ordinance. It was a long time before I did. When I returned to the LORD, I started attending a church near our home. This church was of the same denomination of the one in which I was baptized but they spoke of people being saved.
I now believe that present day churches need to return to the scriptures and their meaning rather than allow the world to shape their theology.
