They are the only times Paul places restrictions on women in leadership. In Corinth he encouraged women praying and prophesying, but then for the sake of order and clarity, gave some guidance to the local situation in which the exercise of spiritual gifts had gotten out of hand. This restriction of leadership is real, but a local one based on specific concerns of faith, not a universal one for the Church. Believers are called to seek the heart of God and refuse to allow secular culture or religious tradition to define truth for the Church. Jesus taught and his following practiced the priesthood of all believers.
Diffused light has little power at all.
For instance, by focusing the power of the sun through a magnifying glass, you can start a fire. But you can't start a fire if the same sunlight is unfocused. When light is concentrated at an even higher level, like a laser beam, it can even cut steel. The principle of concentration works in other areas of our lives too. A focused life will have far greater impact than an unfocused one.
