John 6:44-46

No one can come to Me unless the Father who sent Me draws him [giving him the desire to come to Me]; and I will raise him up [from the dead] on the last day. It is written in the prophets, ‘AND THEY WILL ALL BE TAUGHT OF GOD.’ Everyone who has listened to and learned from the Father, comes to Me. [Is 54:13] Not that anyone has seen the Father, except He [who was with the Father and] who is from God; He [alone] has seen the Father.
