"For the Father judgeth no man, but hath committed all judgment unto the Son: that all men should honour the Son, even as they honour the Father. He that honoureth not the Son honoureth not the Father which hath sent him. Verily, verily, I say unto you, 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. Verily, verily, I say unto you, the hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live. For as the Father hath life in himself; so hath he given to the Son to have life in himself; and hath given him authority to execute judgment also, because he is the Son of man." John 5:22-27
These opening verses remind us that a professed belief in God while discrediting the deity of Christ is not true belief in God at all. The one who does not honor the Son as God, does not honor the Father as God. Man's religion boldly declares a reverent belief in God while denying the deity and saving grace of the Son. Such "belief" is not belief at all. Without belief in the Son, true belief in God is not possible. I Peter declares this to be so when in chapter one verse twenty-one God plainly says that true belief in the Father comes only through belief in the Son, "Who by Him (Christ is the context) do believe in God, that raised Him up from the dead, and gave Him glory; that your faith and hope might be in God." This is not to say that a person cannot give mental assent to the existence of God, but saving faith does not come without belief in the Son.
"...I say unto you, the hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live." Christ is spoken of as the Firstborn from the dead. Prior to Christ, no one rose from the grave to live forever. He was the first to die and rise from the dead, never to die again. This life-giving power positively affects those who die the death of the righteous. Simple belief in Christ as Savior, acknowledging personal sin and having a heart attitude of turning from it, guarantees the repentant sinner a sure place in heaven at the feet of Christ. Without belief in the Son, there is no true belief in God, because the Son has been given all power by the Father, power not only to deliver from death, but also power to bring condemnation upon the ungodly. The day is coming when all the Christ-denying people of the world will be brought to their knees in humble acknowledgment of the deity of Christ. At the Great White throne of judgment, the chance for forgiveness will have past. Let each wise-hearted person come to Christ in humble faith in this life while there is still time, because "it is a fearful thing to fall into the hands of the living God (Heb 10:31)."
