Whatever thing I have denied my selfish desires, Christ denied more to condescend in human likeness and perfect humility.
Whatever temptation I have had to overcome, Christ overcame more on my behalf that he might present a perfect substitute for me before God.
Whatever pain I have endured—whether physical or emotional—in denying the longings of my body and mind, Christ endured more under the just wrath of God on the cross in my place.
Whatever loneliness I feel (imagine: the pathetic loneliness of one who is a temple of the Holy Spirit and a child of God), Christ felt more when the Father turned his back on him because of my sin.
Christ has made a way. He has given me his Spirit. Jesus paid it all, all to him I owe.
So grow up. Be a man. After all, "you have not yet resisted to the point of shedding blood in your striving against sin" (Heb. 12:4).
