Faith in the death of Jesus Christ Crucified on the Cross of Calvary and His resurrection is our only escape route/total-health in this time and for all eternity:

"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], 15 so that whoever believes will in Him have eternal life [after physical death, and will actually live forever].

16 “For God so [greatly] loved and dearly prized the world, that He [even] gave His [One and] [a]only begotten Son, so that whoever believes and trusts in Him [as Savior] shall not perish, but have eternal life. 17 For God did not send the Son into the world to judge and condemn the world [that is, to initiate the final judgment of the world], but that the world might be saved through Him. 18 Whoever believes and has decided to trust in Him [as personal Savior and Lord] is not judged [for this one, there is no judgment, no rejection, no condemnation]; but the one who does not believe [and has decided to reject Him as personal Savior and Lord] is judged already [that one has been convicted and sentenced], because he has not believed and trusted in the name of the [One and] only begotten Son of God [the One who is truly unique, the only One of His kind, the One who alone can save him]." (John 3:14-18 amp)

If we [freely] admit that we have sinned and confess our sins, He is faithful and just [true to His own nature and promises], and will forgive our sins and cleanse us continually from all unrighteousness [our wrongdoing, everything not in conformity with His will and purpose]. (1 John 1:9 amp)

"And anyone who believes in God’s Son has eternal life. Anyone who doesn’t obey the Son will never experience eternal life but remains under God’s angry judgment." (John 3:36 NLT)
