Jesus Marvelled At Unblief! Why?

God certainly is a God a love. He is also a God of wrath. One of His attributes does not negate the others.

God has provided a great salvation. Salvation is coming into a relationship with Him. We are agreed on that.

God does not force that relationship on His redeemed. We are even agreed on that. You may ask, "We are agreed on that? But you are a Mongergist! How can you agree that God does not force a relationship with Himself?" I am glad you asked. The Holy Spirit, through regeneration, changes the sinner's heart making the sinner capable of believing, and believing willingly (Ezk. 36:26). God is the One who moves upon the heart of man, not the other way around (Eph. 2:4-5). God is the One who first loves us (1 John 4:19).

It is just logic, friend. The Synergist's argument fails because it makes the individual the fulcrum on which salvation pivots. Synergists believe God will not violate the will of the creature. He brings the sinner to the water, but the sinner has to decide whether or not to drink. At that moment the sinner is in charge of his own fate. If you disagree with that then you are forced to concede the Monergist position, which is that the Holy Spirit regenerates God's elect. Then, and only then, can the individual exercise faith.

The rest of your post is just a regurgitation of what you already said.

What is most UNFORTUNATE is that you do not see how glorious our sovereign God is. We do nothing to merit our salvation and we can do nothing to keep it. God delivers us from a wicked unbelieving heart that can never believe in Him unless he makes that heart capable. That is the true liberating power of God's unmerited favor, of His grace.
