[LearnsFromMistakes]

Do you not go thru cycles in your relationship with God? Sometimes on your face, approaching the throne. Other times, running into His presence and plopping up on His lap, knowing that you are loved, accepted, and that there is nothing you can do to make Him stop loving you...

You've described the Christian experience. Paul describes his own experience in Romans 7.

The answer to all of your questions is "yes", though many Christians sometimes struggle with assurance. None of this, however, would lead me to approach God as a cosmic Santa Clause who exists for me rather than vice-versa. I am speaking from very strong conviction, out of sincere concern over the Church and the State and not out of malice. God has used conviction in far better men than any of us to accomplish marvelous things in ages past, such as Luther and the Reformation.
