People will do everything they can to try to explain miracles to discredit Jesus ... I should know, i've had about 5 major miracles ... and God always speaks to my Father...
Just once small story ...
My family know an Old man who used to come to our house to eat for 3 years, He needed special cooked food, by Gods grace my mums a brilliant cook, so we cared for this man every way possible and did it in the name of the Lord ... we Told him about Jesus many times and had small debates with him, but he was very stubborn, he was a hindu. He never had any peace. 3 Weeks ago i told him again Jesus, for 30 straight minutes with open eyes he listened to me, then all of a sudden he started talking about money n stuff etc.
Anyway a week ago or so ... God spoke to my Father and told him that man has a few days to live ... Just yesterday we found out that 2 days ago that man passed away. That man's 2 sons are Christians, we know them too, they told us it was great that we witnessed to their Father.
Isn't it great to see that Jesus will place Beleivers all around an Unbeleiver to make sure that on the day of Judgment they dont have an excuse to say "I didn't know your God" etc. Its amazing what God does.
Miracles happen, and the best ones of healing of diseases cancers and sicknesses happen to those that Pray to Jesus.
