All that the Father gives me will come to me, and whoever comes to me I will never cast out. (John 6:37)
πᾶν ὃ δίδωσίν μοι ὁ πατὴρ πρὸς ἐμὲ ἥξει, καὶ τὸν ἐρχόμενον πρὸς ἐμὲ οὐ μὴ ἐκβάλω ἔξω, (John 6:37, NA28)
Note: πᾶν is neuter singular -- everything.
All that (παν ὁ [pān ho]). Collective use of the neuter singular, classic idiom, seen also in 6:39; 17:2, 24; 1 John 5:4. Perhaps the notion of unity like ἑν [hen] in 17:21 underlies this use of παν ὁ [pān ho]. -- Robertson, A. T. (1933). Word Pictures in the New Testament (Jn 6:37). Broadman Press.
This question is consistent with the New Testament early Christian theology. For example, Thomas Aquinas:
- Perhaps some might say that it is not necessary for one to use God’s gift: for many receive God’s gift and do not use it. So how can he say: All that the Father gives me shall come to me? We must say to this that in this giving we have to include not only the habit which is faith, but also the interior impulse to believe. So, everything which contributes to salvation is a gift of God.
- There is another question. If everything which the Father gives to Christ comes to him, as he says, then only those come to God whom the Father gives him. Thus, those who do not come are not responsible, since they are not given to him. I answer that they are not responsible if they cannot come to the faith without the help of God. But those who do not come are responsible, because they create an obstacle to their own coming by turning away from salvation, the way to which is of itself open to all. -- Thomas Aquinas. (2010).

Note on how the verse seems to conflict with itself.
There are difficulties as we try to reconcile the two parts of the verse. But whether we succeed in that or not we dare not abandon the truth in either part. -- Morris, L. (1995). The Gospel according to John (p. 325). Wm. B. Eerdmans Publishing Co.
