Peter Walking on Water

“Without faith it is impossible to please God:” this is true in all relations, and will probably govern the exercise of the powers of the spirit-body. The power is there, but will not act without faith to lay hold on it. Peter had power given him to walk on the water, but he doubted, and therefore his spiritual grapnel lost hold of its catch, and down he went. We have no power given us to walk on the water. To try to do it by faith in the absence of this, would be trying to fasten our grapnel in the air. A right discrimination in these matters will save us from confusion and embarrassment, without leading us into the tremendous mistake of those who regard the faith-performances of the first century as myths.
