I define myself as a Christian. Being a Christian is very difficult sometimes. There are times I want to sin but that is Satan pulling on my chains to try and pull me away from the lord and I cannot allow that to happen ever. I am hoping to continue to grow my relationship with the Lord and continue to allow myself time to forgive the Lord and allow myself to build within him.
