Q1
a. There is no outward evidence in thought, action, or life style to indicate a change within, i.e. no repentance, no change in direction of action. 2 Cor. 7:11
b. The main reason is we do not want to admit we have sinned and are guilty of any thing. We have built our outward life to make all that see us as wonderful, outstanding people. We glory in the adoration by our peers and the persona we have created.
c. 50%, most of the time; the other 50%, sometimes. We are not perfect, yet, and because of that, pride creeps in when we lest expect it.
