The concept of substitution lies at the heart of both sin and salvation. For the essence of sin is man substituting himself for God, while the essence of salvation is God substituting himself for man.
John StottDon't neglect your critical faculties. Remember that God is a rational God, who has made us in His own image. God invites and expects us to explore His double revelation, in nature and Scripture, with the minds He has given us, and to go on in the development of a Christian mind to apply His marvellous revealed truth to every aspect of the modern and post-modern world.
John StottWe are sent into the world, like Jesus, to serve. For this is the natural expression of our love for our neighbors. We love. We go. We serve.
