If we deal with our fears and feelings at a surface level, then we will have experiences at a surface level. If we feel the fears at a surface level and do the next step anyway, then the next step will carry us to the next place, yet with very little depth.
As long as we are afraid of expressing our full selves, we will die a little while we are living. As long as we are afraid, we will never trust the life that has been created for us. As long as we are afraid, we will not trust our Creator and have the amazing benefits that come naturally from a free-flowing God-ordained life. The covenant God has offered to us is there for the taking, yet the acceptance of the covenant is entirely our choice. We have been given free will to choose whether we accept heaven on Earth.
