John 3:10-12

Amplified Bible

¹⁰ Jesus replied, “You are the [great and well-known] teacher of Israel, and yet you do not know nor understand these things [from Scripture]? ¹¹ I assure you and most solemnly say to you, we speak only of what we [absolutely] know and testify about what we have [actually] seen [as eyewitnesses]; and [still] you [reject our evidence and] do not accept our testimony. ¹² 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?
