Then He told them another parable: “The kingdom of heaven is similar to yeast, which a woman worked into a batch of dough [i.e., the amount was over half a bushel], until [the dough] was completely leavened [by it].”
He will cut off [See verse 6] every branch [i.e., follower of Christ] who is in [fellowship with] me that does not bear fruit. And He will prune every branch that does bear fruit, so it will bear more fruit.
but whoever drinks the water I give him will never get thirsty [again]. For the water I will give him will become in him [i.e., in his spirit] a spring of water, bubbling up and producing never ending life.” [See John 7:38].
Therefore, you should put away [from you] all moral filth and overflowing wickedness and humbly receive the word [of God], planted within you [by the Holy Spirit. See John 16:8], which is capable of saving your souls.
