John 6:44 "No one can come to me unless the Father who sent me draws them, and I will raise them up at the last day." John 6:65 "This is why I told you that no one can come to me unless the father has enabled them." John 6:37 "All those the father gives me will come to me, and whoever comes to me I will never drive away." By reading these scriptures it makes it sound like God has only called specific people into his grace. He also said those words are full of the spirit and I don't understand them because I am of the flesh. John 6:63 "The spirit gives life; the flesh counts for nothing." What exactly is the spirit? How do I live by the spirit if I don't even know what it is?
