Brethren in the early Church began to go out with a chip on their shoulder. In criticizing the emperor, idol worship, etc., they precipitated persecutions unnecessarily, thinking that was suffering affliction for Christ, but they were producing the suffering by foolish reasoning. Some were even put to death for castigating rulers at a public ceremony. However, that is not the type of suffering the Lord is looking for in His people. The suffering is by grace and must be received with a humble attitude at all times.
This principle is true, for the more one entangles himself with the affairs of this life, the less he can be a warrior of the gospel. Paul was not saying that those who were married should leave their spouses to preach the gospel to other nations. Rather, each Christian was to soberly consider his present status and not further entangle himself in the affairs of this life. Attention was to be focused on the Christian warfare.
