There is nothing stopping us from being bad and evil through and through but the principles we hold. Think, how many there are who are wicked, and why and how with a conscience that God has bestowed upon all. Even the conscience can be dulled and numbed so deeply that we no longer can feel what is right and be kept captive to this right. Therefore, stand firm and be strong and plant as pillars within your life the words of Jesus Christ, and do not ever abandon them but let them correct you and condemn you and guide you to eternal life. For these, every day, are what stand between your soul and the fires of hell.
You will find the guardian truths of morality in the Bible, which may keep watch over your soul.
