'Worship' is the term we use to cover all the acts of the heart and mind and body that intentionally express the infinite worth of God. This is what we were created for, as God says in Isaiah 43:7, Everyone who is called by my name, and whom I have created for my glory. That means that we were all created for the purpose of expressing the infinite worth of God's glory. We were created to worship.
John PiperAll of history is moving toward one great goal, the white-hot worship of God and His Son among all the peoples of the earth. Missions is not that goal. It is the means. And for that reason it is the second greatest human activity in the world.
John PiperThe formation of the life of a person in the womb is the work of God, and it is not merely a mechanical process but a work on the analogy of weaving or knitting: "Thou didst knit me together in my mother's womb" (psalm 139:13). The life of the unborn is the knitting of God, and what He is knitting is a human being in His own image, unlike any other creature in the universe... The destruction of conceived human life - whether embryonic, fetal, or viable - is an assault on the unique person-forming work of God.
