Christianity has been rebuffed and ridiculed from those early moments in the Garden when our first parents were met with the temptation to not believe. And after that great mess of disbelief was chewed and swallowed, God has been on a rescue mission to recover for His people what they cannot do for themselves.
Christianity is more pervasive and benevolent than most non-Christians want to admit and more victorious and encompassing than most Christians want to believe.
