Gratitude is a handmaiden of contentment. An ever-growing attitude of gratitude will certainly make us more content since we will be focusing more on what we do have, both spiritually and materially, than on what we do not have. But contentment is more than focusing on what we have. It is focusing on the fact that all we do have; we have by the grace of God. We do not deserve anything we have, materially or spiritually. It is all by His grace.
