of my head, therefore my heart faileth me." "My sins are increased over my head so that I am not able to look up." Far better and holier than the best of us, my brethren, was the man who wrote these statements, and left them for an everlasting testimony against those who are pure in their own eyes. If David had such consciousness of sin, what must our consciousness be if we knew ourselves as well? They are the self-blinded, self-hardened, self-deceived, who fancy themselves innocent and glory in their virtue. Even the great apostle called himself "the chief of sinners," and declared that in himself dwelt "no good thing." There is no danger, then, of extravagance in any estimate of our sins of which our arithmetic is capable. So let us proceed a little farther. Take our Lord's summary of the first table of the law: "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength." Here is required the surrender of the whole man as a living sacrifice to his Divine Creator and Sovereign Proprietor. This is his unquestionable claim upon every moment of our existence throughout its immortal duration. A duty this which we cannot omit for a single second without robbing God; and every minute that we neglect it, comprising sixty seconds, we may be said to repeat the sacrilege sixty times; every hour, 3,600 times; every day, 86,400 times; every year, 31,536,000 times; in twenty years, 630,720,000 times; and in forty years, 1,261,440,000 times. But these are sins of omission only, and that in relation to a single phase of duty; add all the other instances, and we must multiply the sum by multiplied millions. Then we must take our positive sins--our violations of the divine law by thought, word and deed--open sins and secret, public and private, personal and social--sins defying all enumeration, and difficult even of classification; and, adding all together, we must multiply the sum by all our faculties, facilities and gracious incentives for doing God's blessed will, and aggravate all by the innumerable mercies and inestimable blessings which he has diffused over our lives as his sunbeams over the earth. And its any thing short of infinite mercy adequate to the forgiveness of such a debt?
