It’s All About Perspective.

Ephesians 3:1 “For this cause I Paul, the prisoner of Jesus Christ for you Gentiles,”
One definition of Prisoner is: a person who is or feels confined or trapped by a situation or set of circumstances.
Other definitions are: a person legally held in prison as a punishment for crimes they have committed or while awaiting trial.
Or a person captured and kept confined by an enemy, opponent, or criminal.

It is 100% your choice to view every situation as a positive or negative. However, your choice will cause you to either speak life or death out of your mouth. Your world is created by the words you speak, and it all starts or proceeds out of your heart (mind). 
If your perspective is negative, you will speak negatively and create situations destined for defeat. If your perspective is positive, you will speak positively and create situations which breed success.
Look at Paul, he acknowledged that he was a prisoner of Jesus. Bound to do his will, and will to suffer whatever was necessary for the benefit of the people he was called to minister to. Paul chose to think positively about being a prisoner of Jesus. He was confined, constrained to do the will of God. But Paul understood, it was not a negative situation because Jesus said my yoke is easy and my burden is light, and ye shall find rest unto your soul (Matthew 11:28-30).
When most of hear the word Prisoner, we can think of no positive connotation. But here Paul challenged us to change the way we think. In Romans 8:28 , we see that ALL things work together for our good. All includes both the bad and good, both the happy and sad, or the for better or worse times. 
We must understand bad, sad, and worse times do occur in our lives from time to time. Change your perspective, and speak life. Create the situation for success. Stop speaking death (defeat and failure).
It’s all up to you. As they say, it’s your world, choose how you wish to live. Be blessed my friends.
