It has been shown that faith is the first principle of the Gospel, and repentance--the forsaking of sin, is the second, and it is now necessary to present the third principle, which is remission of sins. The popular idea in modern Christendom is that repentance of itself brings remission of sins. That is another serious mistake. Payment of debts is not brought about by simply ceasing to get credit; determination to sin no more does not wipe out sins already committed. God is a being of order and of law. He has instituted the means whereby each sinner may receive a cleansing from the past. His laws are as uniform in the spiritual world as in the natural world; obedience to those laws is as necessary in one sphere as in the other. Remission of sins comes to the repentant believer, through baptism, when it is performed by divine direction and under divine authority. Baptism for the remission of sins was preached and practiced by John, the forerunner of Jesus. "John did baptize in the wilderness and preach the baptism of repentance for the remission of sins." (Mark I; 4). Jesus Christ honored that baptism in person and by his teachings. He also sent his Apostles to preach it to every creature. (Matt. XXVII; 19-20, also Mark XVI; 15-13). Previous to preaching that baptism, he instructed his Apostles to "tarry at Jerusalem until they were endowed with power from on high." (Luke XXIV; 47, 49). That power was bestowed upon them on the day of Pentecost, when they were assembled in one place with {215} one accord, and the Holy Ghost was manifested to them in visible form. To the people who gathered to hear the Apostles, forming a great multitude, Peter preached the first Gospel sermon after the resurrection of Christ, as is recorded in the 2nd chapter of the Acts of the Apostles. After testifying of the mission and resurrection of Jesus, the Christ, in response to their inquiry, "Men and brethren, what shall we do?" "Then Peter said unto them, repent and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you and to your children, and to all that are afar off, even to as many as the Lord our God shall call." (Acts II; 37, 38). Three thousand people on that day received the Gospel of Jesus Christ, and were baptized for the remission of their sins.
