John 3:14-16, 31-36

Just as Moses lifted up the [bronze] serpent in the desert [on a pole], so must the Son of Man be lifted up [on the cross], [Num 21:9] so that whoever believes will in Him have eternal life [after physical death, and will actually live forever]. “For God so [greatly] loved and dearly prized the world, that He [even] gave His [One and] only begotten Son, so that whoever believes and trusts in Him [as Savior] shall not perish, but have eternal life.

“He who comes from [heaven] above is above all others; he who is of the earth is from the earth and speaks [about things] of the earth [his viewpoint and experience are earthly]. He who comes from heaven is above all. What He has [actually] seen and heard, of that He testifies; and yet no one accepts His testimony [as true]. Whoever receives His testimony has set his seal [of approval] to this: God is true [and he knows that God cannot lie]. For He whom God has sent speaks the words of God [proclaiming the Father’s own message]; for God gives the [gift of the] Spirit without measure [generously and boundlessly]! [Deut 18:18] The Father loves the Son and has given and entrusted all things into His hand. [Dan 7:14] He who believes and trusts in the Son and accepts Him [as Savior] has eternal life [that is, already possesses it]; but he who does not believe the Son and chooses to reject Him, [disobeying Him and denying Him as Savior] will not see [eternal] life, but [instead] the wrath of God hangs over him continually.” [Heb 3:18]
