A lot of people seem to think that God brings sickness upon people or He uses it as a punishment if you do something wrong but this is not the case. God LOVES us soooo much, He wants us to be healthy and well, and He wants to have a relationship with us and fellowship with us! it is satan who brings sickness upon people because his goal is to steal, kill and destroy (JOHN 10:10).The devil wants to take us out and he uses anything he can to do so including sickness. Alopecia and every other diseases is NOT from God. A lot of people think 'oh well, I guess God just wants me to be sick( or bald), i guess this is how its going to be'...NO! God wants you to have your health, He wants you to have your hair back. It takes faith,and just letting the word of God really sink into your spirit, and just believe that what the Lord says about healing is for you today because God still heals even in this day and age. i just want to give you all a few scriptures to just read everyday. Really let it sink into you until you whole heartedly believe it.
1 peter 2:24
faith for healing- Hebrews 11;1
Also here is a testimony of a woman healed from hair loss. I will also put up other testimonies of people getting healed from diseases that doctors couldnt even figure out.
