John 3:16
John 3:1616For God so loved the world that He gave His one and only Son, that everyone who believes in Him shall not perish but have eternal life.
JWs use this verse frequently but redefine key terms. "Only-begotten" (monogenes) is read as proof that Jesus was literally produced or brought forth by Jehovah — he had a beginning as God's first creation. "Exercising faith" (the NWT rendering of pisteuo) is interpreted as an ongoing activity requiring works: preaching, meeting attendance, organisational loyalty, and endurance to the end. Salvation is thus conditional on sustained performance, not a settled trust in Christ.
The Greek monogenes means "one of a kind" or "unique" (monos + genos), not "only begotten" (which would require gennao). calls Isaac monogenes even though Abraham had other sons — the word denotes uniqueness, not origin. The standard Greek verb pisteuo means "believe" or "trust" — a relational posture, not an activity programme. Modern translations render it "whoever believes in him." The verse presents salvation as arising from God's love and received through trust: God loved, God gave, the believer trusts, the believer has eternal life. The structure leaves no room for organisational mediation or performance-based qualification. Combined with ("has passed over from death to life") and ("so that you may know that you have eternal life"), the gospel offer is present-tense possession, not a future hope contingent on endurance.
The NWT renders pisteuo (pisteuō, "believe/trust") as "exercising faith" — subtly converting simple trust into an ongoing activity requiring effort. This rendering appears across key salvation passages (, 3:36, 6:40) and supports the Watchtower's works-based soteriology by making faith itself sound like a work.
