For if I preach the gospel, it is no glory to me, for a necessity lieth upon me: for woe is unto me if I preach not the gospel.
~1 Corinthians 9:16
God "desires all men to be saved and to come to the knowledge of the truth": that is, of Christ Jesus. Christ must be proclaimed to all nations and individuals, so that this revelation may reach to the ends of the earth:
God graciously arranged that the things he had once revealed for the salvation of all peoples should remain in their entirety, throughout the ages, and be transmitted to all generations.
