There is a subtle but pervasive internal attack on our mind and convictions, to pressure us not to outwardly bear fruit in our worldview, words, actions and witness. In this attack, we are enticed to build the foundation of our faith on what is temporary, self-centered, appealing to our senses and has no eternal value, instead of what is firm, strong, deep and eternally secure. This requires us to break every foundation that is not emblematic of God's call to holiness and faithfulness to Him.  Video of this service is also available:  https://www.youtube.com/watch?v=B9vMj8FWsE8
