John 1:15-18 John bare witness of him, and cried, saying, This was he of whom I spoke, He that come after me is preferred before me: for he was before me. And of his fulness have all we received, and grace for grace. For the law was given by Moses, but grace and truth came by Jesus Christ. No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.
Christ was in existence before John, but after John in public earthly ministry (Matt. 3:11; Lk. 3:17; John 1:31-33) “whose goings forth have been from of old, from everlasting” Micah 5:2 (See also Isa. 9:6-7; Heb. 1:8; Rev. 1:8.)
The Greek word for fullness is pleroma which means abundance, completeness. All needs and lawful wants are promised by the gospel (2Cor. 1:20; Mat. 7:7-11; 17:20; 21:22; Mark 9:23; 11:22-24; John 14:12-17; 15:7, 16; 16:23-26).
Grace upon grace means full grace, according to our needs and wants (Heb. 4:14-16; 10:19-38; Jas. 1:5-8).
The law that condemns in the moral life, and only typifies in the religious life is the law of Moses. First of 13 times Moses is mentioned in John (John 1:17, 45; 3:14; 5:45-46; 6:32; 7:19-23; 8:5; 9:28-29). Grace and truth came by Jesus Christ – this does not mean that there was no law before Moses, or no grace and truth before Jesus Christ. The law itself is truth, and the New Testament is law. There are 1,050 commands in the New Testament. The idea here is that the fullness of grace came by Jesus Christ. One can get today in fullness what men received only in part in Old Testament times.
The Greek word for seen is horao which means to see with the eyes and also see with the mind. That it means here to comprehend fully or understand is clear from the fact that many men have seen God with the eyes (Gen. 18:2, 33; 32:24-30; Exo. 24:10; 33:11; Jos. 5:13; Isa. 6:1-13; Ezek. 1:26-28; Dan. 7:9-14; 10:5-6; Acts 7:56-59; Rev. 4:2-5; 5:1-7). The verse could read, “No man has ever comprehended or experienced God at any time in all His fulness, save the only begotten Son . . . . He hath declared Him.” That Christ is the first to experience God in the fullness of the Holy Spirit is clear from John 3:34; Acts 10:38; Isaiah 11:1-2; 61:1-2 and Luke 4:16-18.
The Greek word for declared is exegeomai which means revealed, expounded; where we get our word exegesis.
