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