What is the most important lesson God taught mankind through the life of salmon?

Salmon live in the sea and then return to their birthplace to spawn.

In that process, just as a salmon endures pain by using its stored energy without eating, we, too, must overcome the pain of being born again by casting off all the bad habits and behaviors we have learnt in this world and strive to return to our eternal heavenly home where Father and Mother dwell.

The Members of the World Mission Society Church of God(WMSCOG) practise the “Words of Mother’s Love” Around the World.

[Romans 12:2]

Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.

God the Mother bestows the blessing of eternal life upon the children of heaven so that they may return to their true home, the Kingdom of Heaven.
To return to the Kingdom of Heaven, one must believe in God the Mother.

[Isaiah 60:1–3]

“Arise, shine, for your light has come, and the glory of the LORD rises upon you. See, darkness covers the earth and thick darkness is over the peoples, but the LORD rises upon you and his glory appears over you. Nations will come to your light, and kings to the brightness of your dawn.”
