John 6:37 All that the Father gives Me will come to Me, and the one who comes to Me I will by no means cast out. 38 For I have come down from heaven, not to do My own will, but the will of Him who sent Me. 39 This is the will of the Father who sent Me, that of all He has given Me I should lose nothing, but should raise it up at the last day. 40 And this is the will of Him who sent Me, that everyone who sees the Son and believes in Him may have everlasting life; and I will raise him up at the last day.”
Many world religions will teach against the clear words of Jesus “I will by no means cast out”, and claim that He can and does cast out those whom He has saved. Roman Catholicism for example will scare and guilt the Catholic to their core and claim they will lose their salvation in an instant just for missing a Sunday Mass. This is why Scripture should always be your ultimate authority, it exposes the false teaching pretty easy.
Jesus explains in John 6:37-40 the will of the Father. This is a pretty important contextual teaching since in other places in Scripture, Jesus warns that those who do “not do the will of the Father” will never be saved. Jesus states that the will is that there are those He is sent, or saved by Him, and that He will never lose them. And to put the nail in the coffin of the “you can lose your salvation” false theology, Jesus then says that those who believe in Him will have everlasting, not temporary, but everlasting life.
Now I have debated many on this passage who conform to the “you can lose your salvation” false theology, and they greatly struggle and can only provide highly laughable refutations. Such as “Jesus won’t cast you out, but you can cast yourself out”, or “Jesus meant this just for the Apostles”. But they stumble to get past “All that the Father gives WILL come to Me” and that by no means He will cast them out. So either Jesus lied or the person trying to refute Jesus did. And we KNOW Jesus could never lie.
So if you ever are in a discussion with someone on salvation, the number 1 discernment key to know whether this person is an actual Christian and part of Jesus’ church is whether they believe provides eternal life with salvation, “by no means” He casts out those He saved. If they dispute this irrefutable fact and claim you can lose your granted salvation, discernment says they are a FRAUD.
