'Happening' in the Bible

“How long has this been happening to him?” Jesus asked his father.“From childhood,” he said.

For most certainly I tell you, whoever may tell this mountain, 'Be taken up and cast into the sea,' and doesn't doubt in his heart, but believes that what he says is happening; he shall have whatever he says.

In the same way, when you see these things happening, know that He is near—at the door!

Day after day I used to be among you in the Temple teaching, and you never seized me. But this is happening in order that the Scriptures may be fulfilled.'
