Correct.

No.
No.
Pride enters the picture when one tenaciously holds on to his position that Jesus meant SOMETHING when He said NOTHING.
NAS John 15:5 "I am the vine, you are the branches; he who abides in Me, and I in him, he bears much fruit; for apart from Me you can do nothing.
Again, to be apart from Christ is to be NOT "in Christ", to be not part of His Body, and hence spiritually dead because Christ is our life (Col 3:4). And when one is spiritually dead, he cannot do any spiritual act; he cannot believe because believing is a spiritual act.
Believing is exercising faith. Faith is fruit of the Spirit (Gal 5:22) and only those "in Christ" can bear fruit. Those NOT "in Christ" cannot bear fruit, and therefore have no faith to exercise.
