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.
Wayne GrudemIt 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.
Wayne GrudemI do not believe that God intended the study of theology to be dry and boring. Theology is the study of God and all his works! Theology is meant to be LIVED and PRAYED and SUNG! All of the great doctrinal writings of the Bible (such as Paul's epistle to the Romans) are full of praise to God and personal application to life.
