Nice one chryon8472, I was going to use those very same verses.
And to coffee, remember that Paul wrote those verses from Romans and the truth that nothing can separate us from the love of Christ, not even ourselves meaning that once we are in Christ, we are in Him forever regardless of what we do.
This is especially important in Paul’s life, a murder who persecuted the church, killed Stephen and referred to himself as the 'chief of sinners". And in spite of all that, God still loved Paul and used Paul for great things. I am confident He can do the same for you.
