DisillusionedJW, yes, I’m a five-point Calvinist. But there’s really no point in debating the finer points of theology with an unbeliever when they don’t accept the very foundation — the gospel.
You say you’ve tried to believe but were never able. There is nothing anyone can say in an appeal to your intellect that would cause you to believe in stories such as animals of all kinds getting on a boat and escaping a massive flood, the sun standing still for a battle, a talking snake in a garden, a talking donkey arguing with a prophet, a burning bush that doesn’t burn up, etc. The ungodly mind is like a brick wall — it has been built to keep God out. Your carnal mind is at enmity with God, it lays up arguments against God, and it is the place of hostility toward God. In order to reach your heart, the only way in is to go around that brick wall and speak directly to your conscience.
First, you need to become aware of the holiness of God. You also need to see yourself in the mirror, in comparison to God, by seeing how you’ve measured up to his standards in keeping his law. God doesn’t demand that you just try your best or give it your best shot — God demands absolute perfection.
Once you have become convicted of your complete failure to live up to this standard and your total inability to do so, you might be ready for the gospel. If so, you might be enabled to believe by the power of the Holy Spirit.
But you will never get anywhere in this regard (except for maybe a false conversion) by debating the existence of God through logic and rationale.
