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 GrudemWhen Jesus invites sinners, 'Come to me, all who labor and are heavy laden, and I will give you rest,' he immediately adds,'take my yoke upon you, and learn from me' (Matt. 11:28-29). To come to him includes taking his yoke upon us, being subject to his direction and guidance, learning from him and being obedient to him. If we are unwilling to make such a commitment, then we have not truly placed our trust in him.
Wayne GrudemThe idea that all the words in Scripture are God's words in such a way that to disbelieve or disobey any word of Scripture is to disbelieve or disobey God.
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.
