In this passage, Paul tells us that despite the struggles he goes through in life, the trials, tribulations, false accusations, rejection of the gospel message by most, he does not become discouraged, will not resort to worldly tactics, and will continue to preach the truth of God's word because the fact that most reject his message is not a reflection on himself, but on Satan who has blinded their minds. Secondly, he does this not for himself but for Jesus' glory and to serve the church. And finally, he does what he does out of love and gratitude for what Christ has done for him.
