What is God?
How do you even begun to think about that question? We sometimes use words like mystery and spirit, but they don’t really tell us anything, they just remind us of what we don’t know.
And yet God had revealed himself to us.
As the scriptures tell us, we know him as creator by his creation; we know him as the Father of our Lord Jesus Christ; we know him as the Son of God, born as one of us; and we receive him as the Holy Spirit. One God, three persons; three persons, one God.
