We must eat and drink the Lord's death and thereby receive His resurrection life.
After eating and drinking, the human body thru the process of digestion, absorption and assimilation, uses food and drink to fuel and supply the body with energy, cell replacement and growth. New cells are formed and old cells are taken down and eliminated. The body is renewed, refreshed and restored. It is the same process with the spirit and soul.
To be transformed we must drink the cup of failure, defeat, bitter circumstance, loss and calamity. It is only thru this process of suffering and death that we can share the throne of life with Christ. Rom 8:17; 2 Tim 2:12. If we suffer, we shall reign with Him. As William Penn wrote and titled his book, No Cross No Crown.
We must come under in order to overcome. We must die in order to live. We must eat death's unfair offerings in order to "partake of the divine nature." 2 Peter 1:4.
When asked by Jesus what He could do for them, James and John replied, "Grant unto us that we may sit, one on thy right hand, and the other on thy left hand, in thy glory." But Jesus replied, "Ye know not what ye ask: can you drink of the cup that I drink of and be baptized with the baptism that I am baptized with?" Mark 10:36-38. He was not speaking of water here. He was talking about drinking and be baptized into His death.
We must assimilate His death into ourselves before we can experience His resurrection life and power. We must become the contents of the bitter cup before we can taste the sweet honey of the goal of the Christian experience. Our minds, emotions and will, our entire personality, must be permeated, changed and transformed by the cross of Christ, by what we spiritually eat and drink. We must be made conformable to His death through the fellowship with Him in His sufferings. Phil 3:10
