Neat preacher on tape, Greg Dickeow says that the hardest thing is to accept Gods unconditional love for us. It's hard. Had similar updragging...not cause Mom was mean, but she had such low self esteem, she had to make it all about being perfect so she thought God would love her and us. Hard road to hoe.
Gregg also says that we can't accept God's love till we love ourselves... and I found that true.
Believe that God's love is perfect and the best part is that He gave His only son to die an agonizing death before we were even born... We can't comprehend that type of love when there was a lot of "conditional" stuff at home.
Just keep telling yourself and confessing to God that you have trouble understanding that type of unconditional love... We have few models here on earth to ever see that.
Confessing it and asking God to show you and grow you...well..it works!
Guess that is why they call it "faith"... beliving in what can't be proven.
Keep the Son in your eyes. We are not defined by other mortals, but by the image of God who made us!
