And daily in the temple, and in every house, they did not cease teaching and preaching Jesus as the Christ. (Acts 5:42)
Once a week is not enough. A one-hour worship service is not a good balance between the onslaught of the world and the teaching and preaching of the gospel. Compare the number of hours spent watching television with a combined time spent in fellowship, worship, praying, Bible-study and service. Unfortunately, statistics say that TV wins. I am not advocating a boycott of television; I am however advocating a greater amount of time be given to that which brings eternal dividends.
May I encourage you to not only attend a weekly worship service, but also a Sunday school class, a mid-week prayer service and a small group fellowship. These combined equate to no more than the amount of television many folks watch in one day. I can promise that your life will be richer for it. Will it be easy? No, it will at first take a fair amount of discipline. There will have to be some priority changes. It will require some sacrifice. However, the fruit that will be produced will be more than worthwhile.
