Again, in Acts xv. 8, 9, it is written with reference to us Gentile sinners: "And God which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as He did unto us; and put no difference between us and them, purifying their hearts by faith." Here we see how the guilt is to be removed from the heart, how we can get a clean heart, obtain the forgiveness of our sins,--even by faith in the Lord Jesus. Depending upon the sufferings of the Lord Jesus in the room of sinners, and depending upon His obedience in fulfilling the law of God, His sufferings are considered as endured by us, His obedience as if found in ourselves: in Him (if we believe on Him) we are considered to have hung on the cross, and therefore were punished in Him, on account of which God, though perfectly holy and just, can forgive us our sins for Jesus’ sake, as well as reckon us righteous, through faith in the Lord Jesus, who in the room of those who believe on Him fulfilled the law of God. I would here by the way especially warn against one error, which is, that persons say, I can believe that Jesus is the Christ, the Saviour, that through Him alone the forgiveness of sins is to be obtained, and I do depend on Him alone for forgiveness, but I desire to know that He is my Christ, my Saviour, and because I am not sure about that, I can have no peace. Now, the Gospel which is preached in the New Testament is not, you must believe that Jesus of Nazareth is your Christ, your Saviour, but that He is the Christ, the Saviour; and if you believe that, you have a right to look upon Him as your Saviour. IV. Question. How may I know that I shall be saved?
