When you look at the circumstances of Paul’s life one might expect to find a bitter, depressed, and frustrated man. Yet what you find is a man who is determined, hopeful, and filled with joy. One might say Paul had an unconquerable spirit.
The Spirit that enlivened Paul’s spirit is the same Spirit given to all believers, the one who seals them and guarantees their future and inheritance. Those who are connected to Christ can, like Paul, cultivate an unconquerable spirit.
