Just yesterday my wife came in our office as I was working and she said she felt like throwing up. I immediately felt the Holy Spirit tell me to lay hands on her and rebuke the sickness in Jesus name. So, I asked if I could lay hands on her and she said sure. I had her lay down and I placed my hand on her stomach and rebuked the sickness. As I rebuked it I felt a humming vibration come from her stomach, much faster than a stomach growling. Almost like the humming of a bee in flight.
After I prayed, she stood up and was surprised, the nausea went away! Sometimes we just have to have an open heart to what God can do. Glory to Jesus Christ for healing her!
PS: If you have a spouse or friend, practice your faith on them (and if you're solo, practice it on yourself!)! Seeing Jesus heal my wife time after time builds up my confidence to lay hands on others :)
