His (Jesus’) begetting from the Father is incomprehensible, for He was carried within the heart, not under the heart, as Mary carried Him in His incarnation. He is a part of the heavenly Father’s heart, of the same substance, of the same power and glory. And just as we know how our neighbor feels about us through his words, so we know what God the Father thinks of us through Christ.
