Worship is what we were created for. This is the final end of all existence-the worship of God. God created the universe so that it would display the worth of His glory. And He created us so that we would see this glory and reflect it by knowing and loving it-with all our heart and soul and mind and strength. The church needs to build a common vision of what worship is and what she is gathering to do on Sunday morning and scattering to do on Monday morning.
John PiperThe missionary question is not, 'Where are there unbelievers?' and then send a missionary there. There are unbelievers everywhere! The missionary question is, 'Where are there people's who don't have any Christians in them or don't have a church strong enough to do the neighbor evangelism that we can do if we just want to do it?' That's the missionary question.
