“For neither at any time used we flattering words, as ye know, nor a cloke of covetousness; God is witness: nor of men sought we glory, neither of you, nor yet of others, when we might have been burdensome, as the apostles of Christ.” 1 Thessalonians 2:5-6 (KJV)
In Thessalonica the apostles could have used their authority to make personal gain from their teaching and preaching. They could have laid down the obligation of meeting the needs of the apostles – they did not.
Far too many times preachers have used the office as a means for personal gain, thus they use soft, cuddly, people pleasing words [flattery] rather than proclaim the unadulterated Word of God, and the truth of the gospel of Jesus Christ.
There is no room for self seeking, self glory in the message of the cross of Jesus Christ, His burial and resurrection. The gospel of Jesus Christ is free to all who will hear and plead for forgiveness, repent of sin, and believe.
