Meditate on this truth today and rejoice in the faithfulness of God:
“The incarnation is the supreme example of fulfilled prophecy, the supreme example of God’s faithfulness to his promises….
What God did when he sent his Son into the world is an absolute guarantee that he will do everything he has ever promised to do.
Look at it in a personal sense: ‘All things work together for good to them that love God’—that is a promise—‘to them who are the called according to his purpose’ (Rom. 8:28, KJV).
‘But how can I know that is true for me?’ asks someone.
The answer is the incarnation.
God has given the final proof that all his promises are sure, that he is faithful to everything he has ever said. So that promise is sure for you.
Whatever your state or condition may be, whatever may happen to you, he has said, ‘I will never leave thee, nor forsake thee’ (Heb. 13:5, KJV)—and he will not. He has said so, and we have absolute proof that he fulfills his promises.
He does not always do it immediately in the way that we think. No, no! But he does it!
And he will never fail to do it.”
