Unless this Christ, the Son of God, is in the central place as the only way to God, there is no gospel.… The times are desperate, they are urgent, and I can think of nothing sadder than for men and women to think they are in relationship to God and then find, at the critical moment, that it has all been a delusion. There are counterfeit experiences; there is an enemy, the devil, who can, according to the apostle Paul, transform himself into a veritable “angel of light” (2 Corinthians 11:14). He will do anything, he will give any kind of experience as long as he can stand between you and this message of Christ. But here is the teaching of the Lord himself: “I myself am the way. No man comes unto the Father but by me.” The apostle Peter, filled with the Holy Spirit, says, “there is none other name under heaven given among men, whereby we must be saved” (Acts 4:12). “For,” says the apostle Paul, speaking of his time in Corinth, “I determined not to know any thing among you, save Jesus Christ, and him crucified” (1 Corinthians 2:2). These men were Jews; they had always believed in God. But what they had come to see was that there is no knowledge of God as Father, no arriving in his presence and spending eternity with him, except through this Christ of God.
