I think it takes discipline and stead-fastness to be a Christian and to try to live spiritual lives. 

This course gives me the opportunity to stay focused on my bible. To read more than the scriptures given to us as classwork and to repeat the things I  previously learned.

I think it is next to impossible to ever really know the bible in its entirety; but we can concentrate on practicing what we learn by being living examples of Jesus' influence in our lives.

When you mix yeast into the dough, it causes the dough to rise; therefore, the yeast changes the composition of the dough. 

The warning concerning the yeast of the Pharisees and Sadducees explains that biblical teachings of Jesus can be contaminated and nullified by the tradition, and non-biblical philosophy they believe and have chosen to live by. 

I think that Jesus wanted the people of Caesarea Philippi to have faith in God.  To trust that Jesus is delivering the word of God, and for them to form their own opinion of Him with the help and guidance of the Holy Spirit; just as Simon Peter had done.
