Certain it is that faith enters into and forms a part of the Gospel. Men are required to believe in God, and in Jesus Christ: and by that I mean, not merely an assent to their existence, but an acceptance of the whole system of truth revealed by them for man's salvation. Faith of necessity is a factor in the Gospel, because it is the incentive to all action; for unless men believe in God's existence, and in the revelations and commandments which he has given them, they will consider themselves under no obligations to obey him; and hence will neglect the things which concern their salvation. It was the knowledge of this fact, doubtless, which led Paul to say: "He that cometh to God must believe that he is (i.e. exists), and that he is a rewarder of them that diligently seek him."[A] And Jesus, too, when he said: "If ye believe not that I am he (the Redeemer, the Son of God), ye shall die in your sins."[B]--had the same thing in his mind. [Footnote A: Heb. xi: 6.] [Footnote B: John viii: 24.] Hence, I say, faith is of necessity a part of the Gospel, a fundamental principle of it; and therefore much importance is given to it by the writers of Scripture. How great that importance is may be learned from the fact that Jesus said, on the one hand, "He that heareth my word, and believeth on Him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life":[C] while on the other hand He said, "He that believeth not shall be damned."[D] [Footnote C: John v: 25.] [Footnote D: Mark xvi: 16.] Belief in God and in Jesus Christ--in the sense I have described in the foregoing--when once fixed in the mind and heart, leads men to obedience to God's laws. It leads them to repentance and every other good work. Repentance is made particularly prominent in the scheme of man's salvation. It was taught by John the Baptist in the wilderness of Judea; the main feature of his mission seemed to have been to call men to repentance. It was taught, too, by Messiah himself. On the occasion of some telling him of certain Galileans whose blood Pilate had mingled with their sacrifices, he said: "Suppose ye that these Galileans were sinners above all Galileans, because they suffered these things? I tell you nay; but except ye repent, ye shall all likewise perish."[E] [Footnote E: Luke xiii: 1, 3.] Going to the time when the Apostles began to fulfill the mission given to them to preach the Gospel, it will be found that this same principle, in connection with others, is urged upon the acceptance of the people. On that occasion Peter preached a discourse in which he proved from the old Scriptures that Jesus was the Messiah, and in answer to the cries of the people, "Men and brethren, what shall we do?" he answered, "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."[F] [Footnote F: Acts ii: 38.]
