Look to the Sacred Records

John Gill:

If the question is concerning the Deity of Christ, his eternal Sonship and distinct personality, look to your way-marks; inquire into the sacred records, and there you will find, that he is the mighty God, God over all, blessed for ever; the great God, the true God, and eternal life (Isa. 9:6; Rom. 9:5; Titus 2:13; 1 John 5:20); that all divine perfections are in him; that the fullness of the Godhead dwells in him; that he is the brightness of his Father’s glory, and the express image of his person; to whom all divine works are ascribed, and all divine worship is given; that he is the only begotten of the Father, the firstborn of every creature; or was begotten before any creature was in being (Heb. 1:3l; Col. 2:9; 1:15); of whom the Father says, Thou art my Son, this day have I begotten thee (Ps .2:7); that he is the Word which was in the beginning with God; and must be distinct from him with whom he was; and in the fullness of time was made flesh; which neither the Father nor the Spirit were (John 1:1, 14); and the same sacred writings will satisfy you about the deity and personality, as well as the operations of the blessed Spirit.
