Faith in Christ Inferred from Faith in God

Matthew Henry, in an exposition of John 14:1: Let not your heart be troubled: ye believe in God, believe also in me, makes plain that a person cannot simply believe in God, but must also believe in Jesus Christ. The natural religion of belief in God cannot Biblically stand without the revealed religion of Jesus Christ. In the first part he describes the objects of our faith, the Father and the Son. In the second part he shows the acts of our faith in Christ must be the same as our acts of our faith in God. In the third part he shows the necessary connection between believing in God and believing in Jesus Christ.
