"When Christians say the Christ-life is in them, they do not mean simply something mental or moral. When they speak of being "in Christ" or of Christ being "in them," this is not simply a way of saying that they are thinking about Christ or copying Him. They mean that Christ is actually operating through them..." (C. S. Lewis - Mere Christianity. Macmillan Publishing 1978. pgs. 64,65)

"Now he whole offer which Christianity makes is this: that we can, if we let God have His way, come to share in the life of Christ. If we do, we shall then be sharing a life which was begotten, not made, which always has existed and always will exist. Christ is the Son of God. If we share in this kind of lif we also shall be sons of God. We shall love the Father as He does and the Holy Ghost will arise in us. He came to this world and became a man in order to spread to other men the kind of life He has – by what I call 'good infection.' Every Christian is to become a little Christ. The whole purpose of becoming a Christian is simply nothing else." (C. S. Lewis - Mere Christianity. Macmillan Publishing 1978. pg. 153.)

"To be in Christ ­ that is redemption; but for Christ to be in you ­ that is sanctification! To be in Christ ­ that makes you fit for heaven; but for Christ to be in you ­ that makes you fit for earth! To be in Christ ­ that changes your destination; but for Christ to be in you ­ that changes your destiny! The one makes heaven your home ­ the other makes this world His workshop." (W. Ian Thomas - The Saving Life of Christ. Zondervan Publishing 1972. pg. 19)

"The Christian life is the life of the Lord Jesus Christ lived nineteen hundred years ago, lived now by Him in you!" (W. Ian Thomas - The Saving Life of Christ. Zondervan Publishing 1972. pg. 120)
