Joseph was in prison even though innocent.
The cupbearer forgot to speak to Pharaoh about Joseph once he got back to serving Pharaoh.
In looking at the long term picture, we can see God working, while in the short time frame of the forgetfulness of the cupbearer, we wonder why God is allowing Joseph to be locked away for so long.
If Joseph had been freed earlier, he may have left the area, since he probably could not have worked for Potiphar any longer.
With Joseph out of the country, Pharaoh may not have known Joseph or been able to locate him.
With Joseph nearby, and with God working thru Joseph, Pharaoh could call upon Joseph and free him because Joseph had God’s plan to save Egypt and the surrounding countries.
When things happen in our lives, and we feel forgotten by God and man, God still is in control and has a plan.
As we suffer in our own prison, whatever it may be, health, finances, etc., perhaps we are in a holding pattern to be available to be used by God in His perfect timing.
We cannot understand why we remain in a situation we know God can change instantly.
We cannot understand why we do not receive healing when we know God can speak and we can be healed, God can breathe into us and we can be restored, God can touch us and we will be renewed.
While in prison, Joseph kept on serving, as if serving God. His mind must have remained pure and God-focused, because when Pharaoh commented on Joseph interpreting dreams, Joseph gave God the glory immediately.
In God’s timing suffering will end. In God’s timing, each who serves Him and waits for Him, even in seclusion, will be called upon to serve God, to proclaim God, and to serve others publicly..
Like Joseph, we need to keep our mind, and attitude God-focused and ready to serve Him at all times.
When the opportunity comes, when freedom comes, we will be able to step to the next level and serve God totally and fulfill His plan.
