When we worship, we first confess our sins to God. Then we offer our whole lives to God in consecration. Finally, after being purified of our sins and consecrating our lives to God, we can have communion and fellowship with him.
“You wish to go back to Egypt? Then you shall go back in the direction of the Red Sea where you started your march. You wish to die in the wilderness? Then you shall die in the wilderness. Do you fear that your children will be slaves in Canaan? Then your children will be shepherds in the desert for 40 years.”
Numbers 11 and John 6 show us that Jesus as our Mediator is better than Moses the mediator between God and Israel. Unlike Moses, even in his darkest hour, Christ did not grumble against God about the rebellious people he was saving. Instead, he prayed for their salvation and for God to be with them.
Paul, therefore, is saying that as Israel crossed the sea, they were united into Moses, who had authority over them from God and who led them in their escape from Egypt and in the crossing of the sea. Continuing with his commentary on the Exodus narrative, Paul points out that Israel partook of the one spiritual food and drink which God gave them through their “baptism” into Moses.
“What the liberal theologian has retained after abandoning to the enemy one Christian doctrine after another is not Christianity at all, but a religion which is so entirely different from Christianity as to be long in a distinct category…. It is at any rate perfectly clear that liberalism is not Christianity.”
