37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
38 For I came down from heaven, not to do mine own will, but the will of him that sent me.
39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
41 The Jews then murmured at him, because he said, I am the bread which came down from heaven.
42 And they said, Is not this Jesus, the son of Joseph, whose father and mother we know? how is it then that he saith, I came down from heaven?
43 Jesus therefore answered and said unto them, Murmur not among yourselves.
44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
You agree All that are given come to Jesus. Not one is lost, but let's examine the next portion of the text that is addressed.
A question might come up. Can anyone who was not given by the Father come to the Son??? vs. 44 says this;
44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
Jesus tells us;
1]All The Father gives shall come
2] No man can come unless the Father gives them
This is why we say it is part of the Covenant of Redemption
There is no one that can be added or taken away .
The multitude is fixed or certain...we cannot add to it, none can be taken away. Jesus again explains it!
39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
These are straightforward teachings.
Reformed people did not write it, be we all by God's grace believe it.
