Satan was the originator of sin

It is not just that we exist and God has always existed, it is also that God necessarily exists in an infinitely better, stronger, more excellent way. The difference between God's being and ours is more than the difference between the sun and a candle, more than the difference between the ocean and a raindrop... God's being is qualitatively different.

God's wisdom means that God always chooses the best goals and the best means to those goals.

God fully knows himself and all things actual and possible in one simple and eternal act.

Election is an act of God before creation in which He chooses some people to be saved, not on account of any foreseen merit in them, but only because of His sovereign good pleasure.

In one sense the doctrine of the trinity is a mystery that we will never understand fully.

The sufficiency of Scripture means that Scripture contained all the words of God he intended his people to have at each stage of redemptive history, and that it now contains all the words of God we need for salvation, for trusting him perfectly, and for obeying him perfectly.
