By Christian Perfection, I mean, 1. Loving God with all our heart. Do you object to this? I mean, 2. A heart and life all devoted to God. Do you desire less? I mean, 3. Regaining the whole image of God. What objection to this? I mean, 4. Having all the mind that was in Christ. Is this going too far? I mean, 5. Walking uniformly as Christ walked. And this surely no Christian will object to. If any one means anything more, or anything else by Perfection, I have no concern with it.
Christian perfection does not imply an exemption from ignorance, or mistake, or infirmities, or temptations; but that it does imply the being so crucified with Christ, as to be able to testify, “I live not but Christ lives in me.” (Galatians 2:20) and has “purified my heart by faith.” (Acts 15.9.) It does imply “the being holy, as he that has called us is holy, in all manner of conversation:” (2 Corinthians 10:5; 1 Peter 1:15;) and, in a word, “the loving the Lord our God with all our heart, and serving him with all our strength.”

Today we continue our celebration/commemoration of Wesley’s Aldersgate experience by highlighting one of his distinctive contributions to theology: Christian perfection.
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.
