My vision of God is dependent upon the condition of my character. My character determines whether or not truth can even be revealed to me." (ouch!) - O. Chambers
Is one's decision to believe in Christ dependent upon the condition of one's character? I guess that's Arminianism, but some would say it at least borders on Pelagianism.
Isn't this the case for all knowing, and not just religious truth? Ask any counselor!
If I have a character that is obstinate and self-centered, I may not be able to receive some truths about my relationship with my spouse. If I am a notorious gossiper, or prone to be jealous, I may not be entrusted with some information that I otherwise might be given.
Similarly, if I have a character which is humble, trustworthy, generous and forgiving,, others may tend to reveal all manner of things to me, knowing that I will not betray them, or use their words against them.
