'Quickly' in the Bible

Therefore repent [change your inner self—your old way of thinking, your sinful behavior—seek God’s will]; or else I am coming to you quickly, and I will make war and fight against them with the sword of My mouth [in judgment].

I am coming quickly. Hold tight what you have, so that no one will take your crown [by leading you to renounce the faith].

He who testifies and affirms these things says, “Yes, I am coming quickly.” Amen. Come, Lord Jesus.
