Do such then believe in Jesus the only Saviour, who seek their salvation and welfare of saints, of themselves, or anywhere else?

They do not; for though they boast of him in words, yet in deeds they deny Jesus the only deliverer and Saviour; (a) for one of these two things must be true, that either Jesus is not a complete Saviour; or that they, who by a true faith receive this Saviour, must find all things in him necessary to their salvation. (b)

(a) 1 Cor.1:13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul? 1 Cor.1:30 But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: 1 Cor.1:31 That, according as it is written, He that glorieth, let him glory in the Lord. Gal.5:4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace. (b) Heb.12:2 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God. Isa.9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. Col.1:19 For it pleased the Father that in him should all fulness dwell; Col.1:20 And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven. Col.2:10 And ye are complete in him, which is the head of all principality and power: 1 John 1:7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. John 1:16 And of his fulness have all we received, and grace for grace.
