This divine communication is meant to prepare believers for the events that are to unfold, emphasizing the urgency and imminence of these events.
The assurance of the words being 'trustworthy and true' is a call to faith for believers, encouraging them to trust in God's ultimate plan and His control over future events.

By affirming the reliability of these words, believers are encouraged to live with hope and readiness, knowing that God's promises are certain and His plans are unfolding according to His divine will.
