Meeting the Condition for Salvation
There is a condition we must meet for salvation. But, thank God for his great mercy, Jesus meets the condition FOR US. Part of his glorious work on our behalf is to give us everything we need for our salvation, including his Holy Spirit to believe. Indeed, we do the believing, but it is the Spirit quickens, who opens our eyes and heart that we might do so.(1)
"The Spirit gives life [quickens], the flesh counts for nothing...No one can come to me unless the Father who sent me grants it."(John 6:63,65)
"All that the Father gives to me will come to me." (John 6:37)
Both statements from the same discussion in John 6 and leave no room for the view that we can come to faith in Jesus on our own or even by cooperation... we come only if we are granted it .. and ALL to whom it is granted will come to faith in Jesus, my Bible declares.
(1) Note: In a similar way God gives us physical eyes, but we do the seeing. What is impossible for man (making himself new eyes) is possible with God.
