and him that cometh to me I will in no wise cast out; such who come to Christ in a spiritual manner, and are brought to believe in him truly and really, he not only receives kindly, but keeps and preserves them by his power, and will not cast them out, or thrust them from him into perdition: the words are very strongly and emphatically expressed in the original, “I will not, not, or never, never, cast out without”; or cast out of doors. Christ will never cast them out of his affections; nor out of his arms; nor out of that family that is named of him; nor out of, and from his church, which is his body, and of which they are Members; nor out of a state of justification and salvation; and therefore they shall never perish, but have everlasting life. The three glorious doctrines of grace, of eternal election, efficacious grace in conversion, and the final perseverance of the saints, are clearly contained in these words.[2]
Jesus’ purpose is to be obedient to the Father. Yes, although He is equal to God (Phil. 2:6-8), He humbled Himself and submitted to God for the glory of the Father’s name, because He loves the Father and always does what pleases the Father (John 8:29, 55), therefore He cannot fail in doing the Father’s will. The will of the Father for the Son is that He would lose nothing, not a single person that was given Him, and raise them (individually and collectively) up on the last day. All those given to Him by the Father are the ones who will never be cast out and will be raised up on the last day, the Day of Resurrection (John 11:24). The Son always does the will of the Father and He will not fail, because He, as God cannot fail! To say that some of them given to Him by the Father will not come to Him or that the Son loses them is to blaspheme the holy Name of the Son. This is the will of the Father for Him, and He never disappoints or disobeys the Father.
John 6:40 For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.
At v. 40, free-willers will object and say, “see, these people have to look and it says everyone, not only the elect”, or other objections of this kind. When one understands what Calvinism truly teaches, they will see that this is not a valid objection to what we actually teach. For indeed, people have to come to Christ in faith, but they come because God has granted them to come (John 6:44, 65). Looking to Christ here is obviously having faith in Him, which is also granted by God to man (Phil. 1:29; Eph. 2:8-9). It is also good to notice that this verse does not say everyone can look at the Son. It gives us the promise that anyone who does, will receive eternal life and will be raised up on the last day. This is the result of God’s work as the entire discussion and context make clear in emphasizing God the Father’s and God the Son’s role in the salvation of the elect. Albert Barnes gives a very helpful comment about John 6:40:
Verse 40. Everyone which seeth the Son, and believeth on him. It was not sufficient to see him and hear him, but it was necessary, also, to believe on him. Many of the Jews had seen him, but few believed on him. Jesus had said in the previous verse that all that the Father had given him should be saved. But he never left a doctrine so that men must misunderstand it. Lest it should be supposed that if a man was given to him this was all th...
