night and day praying exceedingly that we may see your face, and may perfect that which is lacking in your faith?
So Paul was praying night and day for the opportunity of going back and ministering to them again, for he had been with them such a short time, he had not been able to establish them fully in the faith; the understanding of the word. And so, "I'm praying and seeking God that somehow I might be able to come back and complete my ministry to you."
