No, they can't.....that verse doesn't negate the fact that No one can come to Him unless it is granted him by the Father.
Yeah they can if
John 6:45 (KJV)
45 It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me.
if they hear and learn
from the testimony of others
Romans 10:14-17 (KJV)
14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
17 So then faith
cometh by hearing, and hearing by the word of God.
John 1:7 (KJV)
7 The same came for a witness, to bear witness of the Light, that all
men through him might believe.
John 17:20 (KJV)
20 Neither pray I for these alone, but for them also which shall believe on me through their word;
and the scriptures
2 Timothy 3:15 (KJV)
15 And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.
James 1:21 (KJV)
21 Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.
