The question is pertinent. No man can live without appropriating something to his own personality. Property is one of the great natural rights with which we have been invested by our Creator. We could not exist without it.
What are we to do when we consecrate possessions to the Lord? Not to shovel our money into the streets, or to pour it indiscriminately into the treasuries of the nearest institutions, but to become Christ's stewards for the faithful custody and expenditure of this property, making it accomplish the greatest possible good in the well-being of men and the glory of Christ. So much as we can spare from our business and the proper maintenance of our families we must make immediately productive for good in some department of Christ's service, for the Lord at all times condescends to use consecrated substance. But so much as is requisite for the conduct of our business and decent support of those dependent on us may be retained and administered solely for the glory of Him who gave himself for us. Here we must depend each on his own Judgment under the illumination of the word and the Spirit of God.
How may I know that I have laid all on the altar? Self generally rallies on some one point — defends itself in some last ditch. When that is surrendered, the struggle is felt to be over. We know that we have yielded and hung out the white flag, the token of our capitulation. Besides, with all honest souls God is under covenant to reveal to them the state of their hearts. It is the office of the Holy Spirit to hold up a mirror and to furnish a lamp with which we may see our exact visage.
