There is instant coffee, instant oat-meal, instamatic cameras, instant breakfasts. The modern man, woman, and child can not and will not wait for desires to be met.
People today demand instant gratification.
So, at fast food restaurants we can get fast food for fast times. Many camera outlets have a machine that can develop your pictures while you wait. There is drip coffee for those who don't have the time for a percolator. Today, the Lord tells us it takes time for us to grow up, to become mature, in the Christian faith. But even he, after his conversion, spent some 3 years growing and maturing in the faith.
