Paul had introduced them to another world, a higher world of faith, and the Corinthians had preferred the sight world, unable to perceive the interface between the two worlds to be the cross. The Corinthians' dissatisfaction of the Apostolic proclamation, the gospel he had brought them with fear and trembling, the gospel which had delivered them from the world and its old order of sin and death, Paul knew to be a result of their infatuation with the world and their acceptance of its modes of thought. In chapter two Paul diagnoses the problem in the Corinthian church as a deficiency of the Spirit and Spiritual sight. They were still seeing the way the flesh sees, judging the way the flesh judges, and behaving the way the flesh behaves. They were reverting to the powerless and foolish worldly standards from which they were saved.
Children learn by imitation.
They imitate their parents. Imitation does not make you of Christ. Imitation demonstrates that you are of Him. The last thing the Corinthians wanted to do was suffer. Suffering was for the weak and meek, but they considered themselves strong and bold and mature.
