The amazing thing is how that Jesus does as we see in Mark go about doing good and healing ones who are oppressed by satan. This is done by us coming to a place of trusting in Him alone, with the understanding that all the promises of God are for us today. Just as we are held accountable to the promises of God for the blessing that are ours. In the same fasion we are held accountable to the word of God in not obeying the promises as well.
