We assume that a backslider is someone who once knew God and then walked away. But that is not always the case. There are many that sit on pews and never miss a service. They pay tithes and give offerings and will give anything to help others. The Lord wants us to live in victory, being an overcomer and to bring Glory to Him. We must be on guard and be faithful. In this lesson, we learn people can be a backslider and never know it. They can believe they are in the perfect will of God. Peters lack of diligent preparation, which caused him to be caught off guard for what was to follow, his denial that he even knew Christ. The same thing can happen to us!
