John Wesley on Christian Perfection (1)

A year or two after, Mr. Law’s “Christian Perfection” and “Serious Call” were put into my hands. These convinced me, more than ever, of the absolute impossibility of being half a Christian; and I determined, through his grace, (the absolute necessity of which I was deeply sensible of,) to be all devoted to God, to give him all my soul, my body, and my substance.

A Plain Account of Christian Perfection, 11. 367

Do you agree with Wesley that there is no such thing as being “half a Christian”? That we are Christians based solely on the grace and mercy of God? Is it possible for us to give God all our soul, body, and substance? Tell us about your experience with this.
