On that day you will know that I am in my Father, and you in me, and I in you.
The secret to living the Christian life is no secret at all, it is the mystery of Christ in you (Col. 1:27). The indwelling Christ is our hope of intimacy with the Father, he is our joy and forgiveness in the Son, and he is our holiness in the Spirit. As we trust Christ by faith, he gives us the power to love the unlovely, the freedom to walk apart from sin, and grace to experience God’s presence moment-by-moment (Gal. 2:20). The indwelling Christ is joy, liberty, and fullness in the Holy Spirit (Eph. 3:20).
J. Hudson Taylor (1832-1905), founder of the China Inland Mission, reads a letter from John McCarthy on September 4, 1869. McCarthy is a fellow missionary in China and a man who hungers for a deeper, more intimate relationship with Christ. Upon reading McCarthy’s letter, Hudson Taylor declares that he has entered into the “exchanged life.”
McCarthy wrote to Taylor:
I do wish I could have a talk with you now about the way of holiness. At the time you were speaking to me about it, it was the subject of all others occupying my thoughts, not from anything I had read . . . so much as from a consciousness of failure—a constant falling short of that which I felt should be aimed at; an unrest; a perpetual striving . . . .
Then, while reading that same letter, the Holy Spirit reveals the truth of the indwelling Christ to J. Hudson Taylor. Taylor describes the experience:
Abiding, not striving or struggling; looking off unto Him; trusting Him for present power . . . resting in the love of an almighty Saviour, in the joy of a complete salvation, “from all sin”—this is not new, and yet ‘tis new to me. I feel as though the dawning of a glorious day had risen upon me. I hail it with trembling, yet with trust. I seem to have got to the edge only, but of a boundless sea; to have sipped only, but of that which fully satisfies. Christ literally all seems to me, now, the power, the only power for service, the only ground for unchanging joy . . . Not a striving to have faith . . . but a looking off to the Faithful One seems all we need; a resting in the Loved One entirely, for time and for eternity.
After reading McCarthy’s letter of September 4, 1869, Taylor tells a Mr. Judd,
Oh, Mr. Judd, God has made me a new man! God has made me a new man! Wonderful was the experience that had come in answer to prayer, yet so simple as almost to baffle description. It was just as it was long ago [at his conversion], “Whereas I was blind, now I see!”
