The last thing we learn from this is the impossibility of obtaining that of which some men speak--the satisfaction of a good conscience. Some men write and speak as if the difference between the Christian and the worldly man was this, that in the one conscience is a self-reproaching hell, and in the other a self-congratulating heaven. Oh, brethren, is this the fact? Think you that the Christian goes home at night counting up the noble deeds done during the day, saying to himself, "Well done, good and faithful servant?" Brethren, that habit of looking forwards to the future prevents all pride and self-righteousness, and makes our best and only rest and satisfaction to consist in contemplating the future which is bringing us nearer and nearer home. Our motto, therefore, must be that striking one of the Apostle Paul, "Forgetting those things which are behind, and reaching forth to those things which are before, I press towards the mark for the prize of the high calling of God in Christ Jesus." XIII. _Preached January 4, 1852._ CHRISTIAN CASUISTRY. "Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised. Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God. Let every man abide in the same calling wherein he was called. Art thou called being a servant? care not for it: but if thou mayest be made free use it rather. For he that is called in the Lord, being a servant, is the Lord's freeman; likewise also he that is called being free, is Christ's servant. Ye are bought with a price; be not ye the servants of men. Brethren, let every man wherein he is called therein abide with God."--1 Corinthians, vii. 18-24. The whole of these seven chapters of the First Epistle of the Apostle Paul to the Corinthians, is occupied with questions of Christian casuistry. In the application of the principles of Christianity to the varying circumstances of life, innumerable difficulties had arisen, and the Corinthians upon these difficulties had put certain questions to the Apostle Paul. This seventh chapter contains the apostle's answer to many of these questions. There are however, two great divisions into which these answers generally fall. St. Paul makes a distinction between those things which he speaks by commandment and those which he speaks only by permission; there is a distinction between what he says as from the Lord, and what only from himself; between that which he speaks to them as being taught of God, and that which he speaks only as a servant, "called of the Lord and faithful."
