In the book of Matthew, God used angel’s and dreams to speak to Joseph so that God’s purpose of Jesus Christ the Savior of the world being born would be fulfilled. This shows how powerful and fully in control God is and that his purpose and will, will always be done by his divinity. It is the same today, God has the power to communicate and give instructions to his people in any form he chooses to, whether it is through speaking through a person, speaking through a dream or vision, through his word, the Holy Spirit, etc. Many times, we may miss things God is doing because we don’t see everything as God does. But God, is all knowing, all powerful, and he is working all things out according to his will and purpose.
