Hmm i do think that God resists the proud and gives grace to the humble. It was ONLY when Paul humbled himself more grace was given to him, wasnt it? He actually repented and believed.
I am not sure what you are referring to. Here is what Paul was doing before God gave him "more grace"...
Acts 9:1-2... And Saul, yet
breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest, And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem.
This was some of the "more grace" that God gave Paul that he did not give everyone...
Acts 9:3-5... And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven: And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me? And he said, Who art thou, Lord? And
the Lord said, I am Jesus whom thou persecutest:
it is hard for thee to kick against the pricks.
Paul must have been a hard sell. Jesus had to appear to him in person in order for Paul to believe. Would others believe if God gave them the same grace (a physical encounter with Jesus)? I believe so.
In my personal life, I was given "more grace" than other babies in the hospital because although I was born in a third world country with few Christians, God gave me the grace to be born to Christian missionaries. Might the others have believed if God gave them the same grace (Christian parents and Christian preachers)? I believe so.
I believe I would not have gotten saved if God had not given me the "more grace" that he did. Whereas Arminians I have talked with will say they would have gotten saved even if they did not receive the "more grace" that God gave them.
