“For we can do nothing against the truth, but for the truth.” 2 Corinthians 13:8 (KJB)
The truth is what Scripture and the Gospel of Jesus Christ is about. Jesus is the Persona of Truth (John 14:6). The apostle was not going to use the truth to control those who were walking, living in the truth.
Neither can the Pastor, teacher, preacher of today. The word of God is the truth.
I will leave you with some thoughts from a couple of sources:
From F. B. Meyer…
“None can really injure the truth or stop its victorious progress. As well try to stop the sunrise. We often help others most in our weakness, because then we rely most on the Spirit of God. It is the noblest end of life to build up others through our own expenditure, even to the draining of our strength and resources. The world is apt at destruction; and indeed not much art is required for pulling down. But the divine work is to build; we have God’s authority for that.”
and from the Jamieson, Fausset, and Brown Commentary…
“Our apostolic power is given us that we may use it not against, but for the furtherance of, the truth. Where you are free from fault, there is no scope for its exercise: and this I desire. Far be it from me to use it against the innocent, merely in order to increase my own power (2Co_13:10).”
The truth of the gospel is that Jesus Christ came into the world to save sinners; of whom I am the chief sinner. He died for me, and gave me a brand new life. He died on the cross that all who would believe on Him might be saved (John 3:15-18). He was buried, and He rose again.
He lives. He lives. He lives. That is the truth.
