The reason people believe the second lie seems obvious. It allows them to seek what they want. It is also what makes escaping the second lie so hard.
for the first lie, there are several variations. "God can't love me
because I was abused" is often the theme that afflicts some people who
have been sexually assaulted and who blame themselves for someone else's
act of violence. The same is true of people who blame themselves for
mental illness issues that they have no control over or who feel that
some other status renders them to be someone who God can not love.
second group of people to believe the first lie are those who basically
are denying the power of repentance. The "God can love you, but he
will never love me because of my abortion" meme is a well established
one. The call to believe in God's love and the power of repentance is
the most common answer that seems to work for escaping that lie.
third group of people to believe the first lie are a combination of
those two groups, such as alcoholics. There is a large volume of
literature in twelve step programs basically dealing with the fact that a
power higher than yourself can help you even if you have been afflicted
by an addition and even if you have done some terrible things while
under its influence.
entire "you did not cause it, you can't control it, it is not your
fault and God can help you like he helped me" approach of twelve step
programs seems to be the answer for the third group (obviously) as well
as the first group.
for the second lie, I'm not sure of a good way to help people escape
from it. Maybe someone can give me suggestions in the comments?
