There is nothing you can do to help a person who does not believe that they deserve to be loved.
This is Universal Law and without it there would be no Freewill.
For God to make someone accept His love He must override the principle of Freewill which is based upon the Law of attraction. The Law of attraction - or Law of magnetism as we call it - is Freewill in action.
A soul in a dense state of Victimisation will not be energetically attracted towards God's love.
For the individual, the only way out of this state is by going through it. For the individual, the condition itself has to be reason enough to illicit different choices.
I have witnessed this over and over again and as a loving and kind person it can be quite a difficult Principle to accept - however as a person of love, to continually offer love to a soul who is energetically not ready for it, is to not only disrespect yourself, but it is to disrespect the Majestic Governing Principle of Freewill.
God absolutely never forsakes those who come towards Him - even if they have past transgressions.
‘Whoever goes let them go’ might be one of the hardest spiritual concepts to understand.
