It is also important that we do not forget the second half of the verse! We can keep our shell--and that does not have to be Christian shell--but in the end those who are just a shell will be crushed by the Righteous Judge. Including some people who appear to be Christians or even think they are.
22 Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’ 23Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’
24 “Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. 25 The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. 26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.” Matthew 7:22-27
This was how I have felt for quite sometime, but thankfully I can say that is no longer the case! I am so thankful that the Lord has waited patiently and pursued me until I could not go on any longer living as a shell. I am not satisfied with that emptiness, I am now satisfied in being a new creation in Christ. Praise God!
