What does the finished work of the cross do for us, pictured by Israel at the Red Sea?
The finished work of the cross opens our Red Sea ahead, just as Israel was delivered at the Red Sea. It takes us away from the power of the Egyptian army behind us, picturing Satan’s power, because Christ was crucified, buried, and rose from the dead, and salvation is by believing plus nothing.
Les explains that the gospel is the finished work of the cross: Christ was crucified, buried, and rose from the dead, with His shed blood implied. That finished work is what opens our Red Sea out in front of us. It also takes us away from the power of the Egyptian army behind us, or the power of Satan. The context stresses that salvation comes by believing plus nothing, because Christ has done it all; baptism, church membership, and similar additions are not in the verse.
