To walk with the Lord, you need to accept what you have done. We have all sinned (done bad) and we need to be forgiven for that so we can live with Him in Heaven forever. If you are a parent, imaging your son or daughter. If you don't have one, imagine a another family member that you dearly love. Now think about this. What if they had to die? God gave up His only son to die on a cross because He loved us so much. That is indescribable, uncontainable love. In order to walk with the Lord, you have to admit what you've done and give your life and control over to Him. You can't lean on your own understanding, only His. Just talk to Him, and say I want to know You. I am sorry for what I have done. I acknowledge that You are Lord. Once you ask Him for forgiveness He puts it behind Him and never looks back. He loves you as far as the East is from the West. No matter what you have done, no matter how bad, He WILL FORGIVE YOU!

To summarise, Insensibility is a poem in which Owen criticises those who have never experienced war for being insensitive to what the soldiers have to do to survive (become brutes, ignorant of the pain they have to cause).
