2 Of course not! Since we have died to sin, how can we continue to live in it? 3 Or have you forgotten that when we were joined with Christ Jesus in baptism, we joined him in his death? 4 For we died and were buried with Christ by baptism. And just as Christ was raised from the dead by the glorious power of the Father, now we also may live new lives.
Paul’s illustration is baptism. The Greek word has two basic meanings:
(1) a literal meaning- to dip or immerse and
(2) a figurative meaning- to be identified with.
An example from 1 Corinthian 10:2-“And were all baptized unto Moses in the cloud and in the sea.” The nation of Israel was identified with Moses as their leader when they crossed the Red Sea.
When we go into the baptismal waters we are identified with Christ Jesus. If you have accepted Christ as your Savior and have not been baptized you have not identified yourself with Christ Jesus.
