Having an unshakeable foundation is more than knowing intellectually that Jesus Christ is who He says He is and He has done what He has said He would do. It is knowing and having the experience of Him changing your life in which afterwards all things in your life change. It is the "kyregma" or the proclamation of something that has happened and now everything will never be the same. We have been changed from the inside out. Now our lives are on an unshakeable foundation!
