"There is no heaven, either in this world, or the world to come, for people who do not praise God. If you do not enter into the spirit and worship of heaven, how should the spirit and joy of heaven enter into you? Selfishness makes long prayers, but love makes short prayers, that it may continue longer in praise."(Source: Spurgeon's Sermon Notes)
