We are being asked to beg God to "walk through my house, take away all my worries, heal my sickness, etc." Of course, the epistle of James says that we are to pray for the health of the sick, by why not call a doctor, get some medicine instead. After all, God gave us minds to probe and find out what causes illness, and how to cure it. And as for worries, they are things that either we create for ourselves or someone places on us. It's up to us, to solve our own problems that cause our worrying.
