Why don't people ask us about our hope? The answer is probably that we look as if we hope in the same things they do. Our lives don't look like they are on the Calvary road, stripped down for sacrificial love, serving others with the sweet assurance that we don't need to be rewarded in this life.
John PiperThat's who Jesus Christ is. He became the final Priest and the final Sacrifice. Sinless, he did not offer sacrifices for himself. Immortal, he never has to be replaced. Human, he could bear human sins. Therefore he did not offer sacrifices for himself; he offered himself as the final sacrifice. There will never be the need for another. There is one mediator between us and God. One priest. We need no other. Oh, how happy are those who draw near to God through Christ alone.
John PiperWorship is a way of gladly reflecting back to God the radiance of his worth. This cannot be done by mere acts of duty. It can be done only when spontaneous affections arise in the heart.
