John 6:44

No one can come to me unless the Father who sent me draws him, ¹  and I will raise him up at the last day.

So 1:4; Isa 44:18-20; Jer 13:23; Jer 31:3; Ho 11:4; Mt 11:25-27; Mt 12:34; Mt 16:17; Joh 3:3-7; Joh 5:44; Joh 6:39,40; Joh 6:45,65; Joh 6:65; Joh 8:43; Joh 12:32; Joh 12:37-40; Ro 8:7,8; Eph 2:4-10; Php 1:29; Col 2:12; Tit 3:3-5

¹ tn Or “attracts him,” or “pulls him.” The word is used of pulling or dragging, often by force. It is even used once of magnetic attraction (A. Oepke, TDNT 2:503).

sn The Father who sent me draws him. The author never specifically explains what this “drawing” consists of. It is evidently some kind of attraction; whether it is binding and irresistible or not is not mentioned. But there does seem to be a parallel with 6:65, where Jesus says that no one is able to come to him unless the Father has allowed it. This apparently parallels the use of Isaiah by John to reflect the spiritual blindness of the Jewish leaders (see the quotations from Isaiah in John 9:41 and 12:39-40).
