Musings from Readings: The Shape of Sin and Salvation

I've started G.K. Chesterton's Orthodoxy, and in the second chapter, he has the following to say:

"As we have taken the circle as the symbol of reason and madness, we may very well take the cross as the symbol at once of mystery and of health. Buddhism is centripetal (center-seeking), but Christianity is centrifugal (tending away from the centralization): it breaks out. For the circle is perfect and infinite in its nature; but it is fixed forever in its size; it can never be larger or smaller. But the cross, though it has at its heart a collision and a contradiction, can extend its four arms for ever without altering its shape. Because it has a paradox in its center it can grow without changing. The circle returns upon itself and is bound. The cross opens its arms to the four winds; it is a signpost for free travelers."

For a while now, I've heard the adage that each person's sin is infinite. (From now on, I will speak personally.) If my sin is infinite, how does that stack up to a God who is also proclaimed infinite by Scripture? I think Chesteron is on to something with his assessment of a circle as being infinite, yet limited in size, while the cross is infinite and unbound. What a thought! My sin continues its infinite race, amassing lap after lap of sin, but its circular path can never get wider, while this infinite transgression is swallowed up in the un-bound infinite cross of Christ. Praise the Lord oh my soul!

"When Satan tempts me to despair, and tells me of the guilt within, upward I look and see Him there, who made an end to all my sin."
