Who says we don't all have holiness within us? You must not have children??? Does any child come into this world and immediately improve upon holiness within? On the contrary, immediately self-perservation is evident and once mobility and other abilities develop, serious unrighteousness and pride issues unfold. They'll continue to do so unless someone bends that child's sinful will toward righteousness. Now don't you believe that the Creator of man would provide a single way to fix the problem so we all wouldn't pridefully construct our own remedy? He did. And man still constructs and works infutility to the contrary of God's design0it is narrow and limiting...the "pride" problem and sin nature requires just that).
