For there is one God, and one mediator between God and men, the man Christ Jesus,
The knowledge of one God for all men would be to no avail if there were no mediator to reconcile man to his God. For God is so holy and man so sinful that corrupt man could not appeal to a holy, sinless, and divine God on his own (Isaiah 59:1-2). Necessity demanded that Jesus become the incarnate; thus, being God and man, He was able to bring about a reconciliation in and through himself, that being on conditional terms. Therefore, Jesus is the only mediator for all who will come to the knowledge of the truth and obey the gospel.
