Some Believers do not under their walk in Christ. Hence, the reason for backsliding when obstacles placed before them as they try to work out their own salvation. The name Pligrim's Progress speaks volume. It is gradual progress made with each step in Christ. It is a wonderful way to teach and encourage new believers that at every stage or level of our walk in Christ, He has already blessed us, we have the victory in Him and we are conquerors. It does not matter what comes up as we walk this pathway our eyes will forever be focused on HIM.
A great way to show and teach your children the trials and tests of everyday and how to make the right choice. A very clear vision that Heaven is real and Hell is real and how close you can be to Heaven, but still not make it in. It makes you really stop and think about whether you are on the right path or not. It shows how you need a firm foundation in your Christianity to defeat the devil.
