2. Belief in man, as a child of God, whose spirit is destined to live forever (Genesis 2:7; 2 Corinthians 5:1; Ecclesiastes 12:7; Matthew 6:25; 5:29,30).
3. Belief in sin which taints and corrupts the heart of man, making it finally, if unchecked, the dwelling place of all evil. The effects of sin are everywhere plainly manifest. Men not only sin through ignorance and carelessly but willfully. The worst sins are those which are of the spirit, anger, pride, malice and envy (Isaiah 53:6; 64:6; Romans 3:23; 1 John 1:8; Romans 1:18-3:23; 8:7).
4. Belief in Jesus Christ, the Son of God and the Saviour of men, who can cleanse the heart of man and save him from his sins. Jesus Christ came not only to reveal God, the Father, to man but also to purge his heart from evil. "He is the propitiation for our sins" (1 John 2:1,2; Romans 8:34; Hebrews 7:24,25; Matthew 20:28; Romans 3:24,25; 5:8; 8:3; Galatians 3:13; 2 Corinthians 5:21; 1 Corinthians 1:30; Matthew 9:2-6).
5. Belief in the sanctifying power of the Holy Spirit (1 Corinthians 6:11; Ephesians 3:16; Galatians 5:22) who "testifies of Christ, as the Saviour of sinners, unites us to Him by faith, and makes us partakers of all His benefits." Jesus said, "When the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, He shall testify of Me" (John 15:26). "The Spirit of truth … will guide you into all truth…. He shall glorify Me: for He shall receive of Mine and shall show it unto you" (John 16:13,14; 14:26; 1 Corinthians 12:3; Titus 3:5,6; Matthew 28: 19; John 3:5,6).
6. Belief in the resurrection and the life to come, the issues of which are declared to be eternal. "The hour is coming in which all that are in the graves shall hear His voice, and shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation" (John 5:28,29; Matthew 25:31-46; 25:1-13). The great rainbow of promise that spans the future, for those who trust in Christ, is in the fact that He said, "I am the resurrection and the life: he that believeth in Me, though he were dead, yet shall he live. And whosoever liveth and believeth in Me shall never die" (John 11:25,26; I Thessalonians 5:23; John 6:47; 14:2,19). The resurrection body "will be spiritual, immortal, incorruptible, and like unto the glorious body of Jesus Christ" (Philippians 3:20,21; 1 Corinthians 15:20-23,35-57).
Definiteness.—There is a marvellous directness and definiteness in the statements of the New Testament writers, in proclaiming the Christian faith, because they believe that they are dealing with the tremendous facts of life and destiny. God has manifested Himself and spoken in Jesus Christ as He has never manifested Himself before. "God who at sundry times and in diverse manners spake in time past unto the fathers by the prophets, hath in these last days spoken unto us by His Son, whom He hath appointed heir of all things" (Hebrews 1:1,2). The eternal things of God, kept secret from the foundation of the world, are now made known to man; why should he not, in spite of any punishment or threatened ignominious death, proclaim these truths definitely and plainly to his fellow man (Acts 4:13-20)?
The keynote of all of Paul's work is sounded in a very definite and direct way in his first Epistle to the Corinthians (2:2,5) where he says, "For I determined not to know anything among you, save Jesus Christ and Him crucified…. That your faith should not stand in the wisdom of men but in the power of God." Paul consistently maintains throughout his Epistles that the sole basis of salvation is the grace of God through Jesus Christ, to be appropriated by faith on the part of man.
TESTS OF CHRISTIAN FAITH
Effects Upon Men and Institutions.—Jesus Christ was ever urging His disciples to test His words and principles. He declared the difference between true and false prophets could be known by their fruits. He said, "Do men gather grapes of thorns or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit … wherefore by their fruits ye shall know them" (Matthew 7:15-20). When Thomas expressed doubt of His resurrection, Christ gave him ample opportunity to test its reality (John 20:24-29). Christ's challenge to the world is, "Try Me!" "Come and see what I can do!"
What kind of men has the Christian faith made? What kind of communities has it produced? Two pertinent questions are asked in a recent book of sermons, What would be the effect upon this world if everybody was a consistent Christian? What would be the effect upon this world if everybody was a consistent infidel? "The argument is a crushing one, for of a truth Christianity can stand such a test with a glory that would astonish even the most ardent enthusiasts. And it is the one test, let it be admitted with sorrow, that a reviling world is not willing to have it judged by."
