freedom in Jesus

I found this article in a british newspaper, and I know it is super nasty to look at, so I apologize in advance. It is the story of a Jehovah's witness who suffered from a rare blood disease that caused a slight deformity in his mouth, but because of his unwillingness to receive a blood transfusion, it is now over 12 pounds and threatening his life. I couldn't stop thinking how sad it would be to serve a God who wouldn't want you to get a blood transfusion, but would allow you instead to deal with this. How could he not see how much more God has for him? How could you go through life with that on your face?!!! It made me so grateful for the freedom I have in Christ, but it also made me think about my own life. How often do I allow little things to fester in my heart like unforgiveness, pride, lust, or bad attitudes without seeing how ugly they are to God. Am I walking around with spiritual tumors that I don't realize I have? Or am I just not letting God operate on them? What will it look like if I do nothing?

Galatians 5:13 "for you have been called to live in FREEDOM, but don't use your freedom to satisfy your sinful nature, instead use your freedom to serve one another in love"

Thank you Jesus for setting me free, and now may I serve you by serving others.
