In 2 Tim. 4:7, Paul writes as it were his own epitaph.
It's something you might say after crossing the finish line of a marathon or after completing a monster workout at the gym.
"I have fought the good fight."
"I have striven the good strife."
A battle is raging in the spiritual realm today. It may be invisible, but it is real. Paul uses a metaphor here that refers to a contest in an arena. Whoever engages today in the theological disciplines steps into a battlefield, not a playground. Some battles are mere skirmishes. Others are more important. On rare occasions, there are major battlefields that require keen discernment and a courageous counter-strategy. This calls for a strong mind and an unintimidated will.
I will say it plainly. If you are a pastor or church leader and desire to do anything about this assault on biblical authority, you will need the biblical languages. No matter the size or scope of the attack, you must be able to allow the word of God to speak for itself clearly and unambiguously. You cannot guess as to what the text is staying. It takes keen eyes to see the dangers and to fight for what's right.
