Sin is any failure to conform to the moral law of God in act, attitude, or nature

God eternally exists as three persons, Father, Son and Holy Spirit, and each person is fully God, and there is one God.

If God is not unchanging, then the whole basis of our faith begins to fall apart, and our understanding of the universe begins to unravel. This is because our faith and hope and knowledge all ultimately depend on a person who is infinitely worthy of trust - because he is absolutely and eternally unchanging in his being, perfections, purposes, and promises.

I think that ultimately we will attain much more depth of understanding of Scripture when we are able to study it in the company of a great number of scholars who all begin with the conviction that the Bible is completely true and absolutely authoritative.

The clarity of Scripture means that the Bible is written in such a way that its teachings are able to be understood by all who will read it seeking God's help and being willing to follow it.

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.

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