14Now the disciples had forgotten to bring any bread; and they had only one loaf with them in the boat. 15And he cautioned them, saying, “Watch out—beware of the yeast of the Pharisees and the yeast of Herod.” 16They said to one another, “It is because we have no bread.” 17And becoming aware of it, Jesus said to them, “Why are you talking about having no bread? Do you still not perceive or understand? Are your hearts hardened? 18Do you have eyes, and fail to see? Do you have ears, and fail to hear? And do you not remember? 19When I broke the five loaves for the five thousand, how many baskets full of broken pieces did you collect?” They said to him, “Twelve.” 20“And the seven for the four thousand, how many baskets full of broken pieces did you collect?” And they said to him, “Seven.” 21Then he said to them, “Do you not yet understand?” (Mark 8:14-21, NRSV)
Yeast is not always about bread. But once you put the yeast in, you can not take it out…
It is like pouring salt and sugar together and then trying to separate them. It isn’t possible. We need to be aware of what is happening around us and who the people are that are influencing our life.
Do not let those who will bring you down have an effect on you.
Let God permeate your life and work in and through you.
