If you are now going through testing, there are three things you should especially remember.
First, God's way is the wisest way. Training is always accompanied by some type of hardship.
Even athletes realize they cannot properly train without giving up some of the pleasures of life and enduring the hardship of training. God trains us through chastening.
Second, God's time is the best time. God was working out His purpose through Joseph. It was impossible for Joseph to realize it at the time, but later he could look back and see that God's time had been exactly right--everything had worked out.
But imagine the lonely years of waiting. God does not act too early nor too late. He is never in a hurry but accomplishes things in His own time.
Too many of us either lag behind or run ahead of God's time. But we need to remember that the clock of divine providence keeps strict time. Because of our circumstances it may appear to be slow at times and fast at others, but the all-wise God knows precisely when to act.
Third, God's grace is sufficient. He will give us the grace we need to be patient.
James 1:4 says, "But let patience have her perfect work, that ye may be perfect and entire, wanting nothing." The word "perfect" means "mature" or "complete." God is seeking to teach us valuable lessons so we will be mature believers.
"Behold, happy is the man whom God correcteth: therefore despise not thou the chastening of the Almighty" (Job 5:17).
