Repentance. A good message about the danger of falling into sin and of trusting in ourselves. In the first point of the sermon, the preacher speculates too much, translating the physical into spiritual, especially on the comments on John 13:23-24. Very good the call to repentance.
Great difference. God made great difference between His people and the Egyptians. I wonder if the text doesn't say that there was light not only in the homes of the children of Israel, but that there was the light of the sun where they lived.
