(J.C. Ryle, "Holiness, Its Nature, Hindrances, Difficulties, and Roots")

A holy man will strive to be like our Lord Jesus Christ. He will not only live the life of faith in Him, and draw from Him all his daily peace and strength — but he will also labor to be conformed to His image (Romans 8:29). It will be his aim . . .
  to bear with and forgive others — even as Christ forgave us;
  to be unselfish — even as Christ pleased not Himself;
  to walk in love — even as Christ loved us;
  to be lowly-minded and humble — even as Christ humbled Himself.

A holy man will remember . . .
that Christ would continually deny Himself in order to minister to others;
that He was meek and patient under undeserved insults;
that He thought more of godly poor men, than of kings;
that He was full of love and compassion to sinners;
that He was bold and uncompromising in denouncing sin;
that He sought not the praise of men, when He might have had it;
that He went about doing good;
that He was separate from worldly people;
that He continued instant in prayer;
that He would not let even His nearest relations stand in His way, when God's work was to be done.

All these things, a holy man will try to remember. By them, he will endeavor to shape his course in life.

He will lay to heart the saying of John: "He who says he abides in Christ, ought himself also so to walk, even as He walked" (1 John 2:6); and the saying of Peter, that "Christ suffered for us, leaving us an example that you should follow His steps" (1 Peter 2:21).

Happy is he who has learned to make Christ his "all," both for salvation and example! Much time would be saved, and much sin prevented — if men would oftener ask themselves the question: "What would Jesus have said and done — if He were in my place?"
