"Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened to you: But rejoice, inasmuch as ye are partakers of Christ's suffering; that, when His glory shall be revealed, ye may be glad also with exceeding joy." (1 Peter 4:12-13)
When you know yourself to be a child of God, but you find yourself literally going through hell; "Think it not strange..." When you can't understand why some sudden tribulation has caused you to feel shipwrecked; a sort of falling apart of things; "Think it not strange..." This is a time to, "Lean not unto your own understanding." (Proverbs3:5) Trust that the Lord has not forsaken you.
It is possible you could be experiencing chastisement; which is not pleasant. In which case, bare it with a penitent heart and gratitude that the Lord would love you enough to chasten you. (Hebrews 12:11) Or perhaps you clearly don't understand the reason; it’s just a storm out of nowhere. In either case, you would do well to abandon your own understanding and consistently declare the Lord to be the anchor of your soul. (Hebrews 6:19)
Another aspect of suffering revealed in scripture is the just suffering for the unjust; a good explanation for the age old question; Why do bad things happen to good people? Just as Christ, the just, was made to suffer for the unjust; so we also become partakers of Christ's suffering.
Many say they want to be more like Christ; beware it requires suffering unjustly. So we must learn how to endure this with a Christ-like attitude; remembering how Christ suffered for us all. "For it is better, if the will of God be so, that ye suffer for well doing, than for evil doing. For Christ hath also once suffered for sins, the just for the unjust, that He might bring us to God ..." (1st Peter 3:17-18)
When Job suffered blindly he boldly declared, "Though He slay me, yet will I trust Him:" (Job 13:15) Job could no longer trust in his wealth, it was gone; or in his friends. He could not trust in his wife or even in himself. He was rendered completely helpless but for the mercy of God. Job was made to recognize the shéer frailty of his existence and ultimate dependency upon God's mercy.
After a Job season we are changed to have a much greater dependency upon God the Lord. It is a difficult task to break us from depending on ourselves. But its worth it to reach the revelation of abandoning self-reliance for the freedom of leaning and truly depending upon the Lord. Often our little 'self-indulgent will' is a hindrance to the true will of God. But a wonderful freedom comes with releasing our cares to Him. Remembering that, "In weakness is His strength made perfect." Just remember there is no place we can be that He is not; even in the belly of a whale. Jonah, while in the belly of the whale said, "I cried out by reason of mine affliction unto the Lord, and He heard me; out of the belly of hell cried I, and Thou heardest my voice." (Jonah 2:2) "...yet hast Thou brought up my life from corruption, O Lord my God. When my soul fainted within I remembered the Lord; and my prayer came in unto Thee, into Thine Holy temple." (Jonah 2:6-7) This is a journey that will press you beyond measure. I like to think of these as our Job and Jonah experiences. God is gracious enough to allow us to reference their reactions to being pressed beyond their understanding of life. Jonah said, "I cried out of the belly of hell and God heard me." Job said, "Though He slay me, yet will I trust Him:" "Think it not strange; the fiery trials..." we must sometimes endure.
But just know that you must abandon your own understanding to survive it; and further declare, "In Thee, O Lord, do I put my trust..." As fire is a refiner so are these fiery trials meant to refine us. "Behold, I have refined thee, but not with silver; I have chosen thee in the furnace of affliction." (Isaiah 48:10) So, "Beloved, think it not strange..."
Isaiah 50:10 -- Who is among you that feareth the Lord, that obeyeth the voice of his servant, that walketh in darkness, and hath no light? Let him trust in the name of the Lord, and stay upon his God.
