Hmm .... here something on suffering and knowing the God of resurrection:
----------------------------------------------
But  why do we stress the distinction between the living God and the God of  resurrection? Because, while the living God can perform many acts on  man's behalf, the nature of the living God cannot blend with the nature  of man. When, on the other hand, the God of resurrection works, His very  nature is wrought into the nature of man. Brothers and sisters, please  note carefully that even when the living God has performed some act on  your behalf, after that act as before it, He is still He and you are  still you. His working on your behalf does not impart anything of His  nature to you. The living God can work on behalf of man, but the nature  of the living God cannot unite with the nature of man. On the other  hand, when the God of resurrection works, He communicates Himself to man  by that which He does for him. Let me cite two illustrations.
When  the children of Israel were in a hopeless plight in the wilderness, the  living God opened a way for them across the Red Sea. The dividing of  the Red Sea was a miracle which demonstrated to them that God was the  living God, yet that miracle performed for them did not bring any  measure of the life of God into them. They witnessed many other divine  acts in the wilderness—e.g., God gave them bread from heaven and water  out of the rock—but despite those and other wonders performed by God for  them, nothing of God Himself was thereby imparted to them.
In  contrast to this, the apostle Paul testifies to knowing not only the  living God, but also the God of resurrection. Paul was so sorely tried  that he despaired of life, but it was thus he learned to trust in the  God who raises the dead. When the God of resurrection acted on his  behalf to raise him from the dead, that divine act not only accomplished  something for Paul; it also communicated God's own nature to Paul.
Brothers  and sisters, do discriminate here. The miracles wrought for Israel in  the wilderness were acts of the living God; but despite the many  miracles wrought for them, nothing of God was wrought into their  constitutions. The miracles wrought for Paul were wrought by the God of  resurrection, and each fresh miracle wrought a fresh measure of God  Himself into the life of Paul. Alas! though generations have passed  since the resurrection, many Christians are almost ignorant of the God  of resurrection and are only interested in the living God. Let me try  and bring this matter home to our daily lives.
A brother becomes  seriously ill. His case is considered hopeless, but God has mercy on him  and works a miracle on his behalf so that he recovers. Thereafter, he  testifies to the fact that God is the living God. Yet within a short  time of his recovery he plunges right into the world. Even when he is  living in the world, he still remembers that God is the living God and  that God preserved his life from death. But he has experienced no  increase of divine life; he has only experienced a miracle of healing.
Another  brother becomes ill. Day after day passes without a vestige of  improvement. For long he keeps hovering at the edge of the grave. Then,  when he has completely despaired of life, in the depths of his being he  gradually becomes aware of God. Resurrection life begins to work within,  and he awakens to the fact that this resurrection life is a life that  can overcome all affliction and can even swallow up death. He is still  conscious of much weakness and is sorely tested; nevertheless, the  realization deepens that God is not working to make His might known in  external acts, but is working to impart Himself. Light breaks upon him  gradually, and gradually health returns. This brother does not just  experience a healing; he comes into a new experience of God. The other  brother could testify to a miracle wrought in his body, and shortly  after could plunge right into the world; but if this brother gives a  word of testimony there is nothing sensational about it, and there is no  stress on the healing; yet, you meet God in his life.

What  is the significance of suffering? This, that the devastation it brings  to the old creation provides an opportunity for the God of resurrection  to impart Himself to His creatures, so that they emerge from the death  process with a divine element in their constitution. The primary purpose  of suffering in this universe, particularly as it relates to the  children of God, is that through it the very nature of God may be  wrought into the nature of man. "If indeed our outward man is decaying,  yet our inward man is being renewed day by day." Through a process of  outward decay an inward process is taking place that is adding a new  constituent to our lives.
Beloved brothers and sisters, through  hardship and pressure a divine element is being wrought into the very  fabric of our beings, so that we cease to be colorless Christians, but  have a heavenly hue imparted to our lives that was lacking before.  Whatever else suffering may effect in this universe is incidental; this  is primary—to bring those whom the living God has made possessors of  created life into the uncreated life of the God of resurrection. It is  in the death experiences which come through suffering that the life of  the creature is blended with the life of the Creator. We may know the  living God without such drastic experiences, but only through death can  we come to an experimental knowledge of the God of resurrection.
Suffering  is the God-appointed lot of the Christian. The Christian's happiness is  not to be found in external things, but in learning to enjoy God  Himself in the midst of trial. Paul and Silas could rejoice and sing His  praises while they were in prison, because their happiness did not come  from outer circumstances, but from an inner enjoyment of God. In Paul's  short letter to the Philippians, written during his imprisonment, there  are over a score of references to joy. In deep distress he could still  be joyful because in his affliction he was learning to know Christ, to  appropriate Him and to enjoy Him. His outward circumstances were all  conducive to sorrow, but it was in sorrow that Christ was imparted to  him as the source of his joy.
