As a congregation member of the Watchtower society my understanding of John 3:16 was blurred. It reads in the Amplified Bible, Classic Edition (AMPC):
“For God so greatly loved and dearly prized the world that He [even] gave up His only begotten (unique) Son, so that whoever believes in (trusts in, clings to, relies on) Him shall not perish (come to destruction, be lost) but have eternal (everlasting) life.”
Some doctrines of the WT organization claim that God’s love for mankind was not his primary motivation to save mankind. But we should trust John 3:16.
Also Jesus’ love for mankind is not enough taught within the WT organization. But apostle Paul taught it:
Galatians 2:20 Indeed, the life that I now live in the flesh I live by faith in the Son of God, who loved me and handed himself over for me.
Jesus himself assures about his love for those who believe him. John 15:9 ASV:
“As the Father has loved me, so have I loved you. Abide in my love.”
Apostle Paul again refers to Jesus Christ’s love for those who believe him.
Ephesians 5:25 Jubilee Bible 2000 (JUB): “Husbands, love your wives even as the Christ also loved the congregation {Gr. ekklesia – called out ones} and gave himself for her,”
Some interesting facts about the origin of the Greek word ekklesia that is mostly translated as church.
