Is there ANY relationship between salvation and baptism, specifically AFTER salvation and not CAUSING salvation, I found this verse about baptism identifying someone with the death and resurrection of Christ (which is required belief for salvation):
3 Or do you not know that all of us who have been baptized into Christ Jesus have been baptized into His death?
4 Therefore we have been buried with Him through baptism into death, so that as Christ was raised from the dead through the glory of the Father, so we too might walk in newness of life.
5 For if we have become united with Him in the likeness of His death, certainly we shall also be in the likeness of His resurrection,
What would be the relationship between these verses and infant baptism?
Does not salvation constitute becoming IN Christ Jesus?
