'Happen' in the Bible

I myself have [actually] seen [that happen], and my testimony is that this is the Son of God!”

If I told you earthly things [that is, things that happen right here on earth] and you do not believe, how will you believe and trust Me if I tell you heavenly things?

Then Jesus said to him, “Unless you [people] see [miraculous] signs and wonders, you [simply] will not believe.”

Afterward, Jesus found him in the temple and said to him, “See, you are well! Stop sinning or something worse may happen to you.”

But when He, the Spirit of Truth, comes, He will guide you into all the truth [full and complete truth]. For He will not speak on His own initiative, but He will speak whatever He hears [from the Father—the message regarding the Son], and He will disclose to you what is to come [in the future].
