@Psalty. I often disagree with
@JonC but what he says here is certainly true:
The reason we wrangle with these concepts is that both are found in scripture. I am not in any way wanting you to become a Calvinist. Regarding man and his fallen nature, I just believe that by nature and by God's design, we were made to serve and have fellowship with God. When our first representative parents fell due to deliberate rebellion against God we felt the effects of that. We are unable, in our natural state, to fix that situation. Worse yet is that the reason is we don't really want to. I'm willing to admit that maybe Flowers and Lennox are right in that we all retain enough natural ability to at least figure out that we are in trouble and need to come to God, with only natural inducements like the message of the gospel, or the verbal explanation of salvation. Or maybe the Arminians are correct in that the Holy Spirit works and is necessary but he works in a persuasive manner, not decisively.
Or maybe it's in truth, a combination of things. In the same area as my quote from John Owen above, he says some things that indicate that using your natural intellect to attend services and the means of grace and reading scripture can at least increase the chance of further grace being given. And then he warns not to trifle with grace or light given, lest it be withdrawn and you will never come to Christ - and it will be totally on you, due to your resistance. Ask me to explain that, coming from the pen of a famous high Calvinist.
All these theological systems are good guardrails to keep individuals and churches on the best path. I find them all unsatisfactory as a point by point rule of how I need to think and believe. That should be reserved for scripture only. So do you reject all the systems and just use the Bible. You could, but most of the cults and heretics claim exactly that. With a theological system you at least have a touchpoint for reconciling difficult passages or apparent contradictions. So I find them useful. Keep reading.
