what greater work

The Word of God says that -
the gift of prophecy will be no more
the gift of tongues will be more
the gift of knowledge will be no more
(1 Corinthians 13:8)
But love shall be forever
For God is love, for He first loved us and He showed us His love in and through His Son, Jesus Christ, our Savior and Lord.

So, from an eternal perspective (which we are to have as believers) when Jesus Christ said
"Truly, truly, I say to you, he who believes in Me, the works that I do shall he do also; and greater works than these shall he do; because I go to the Father.” (John 14:12‑13)

What is the greatest work of God that we can participate in ?

The saving love of God poured out for people to change their eternal destiny !

We have been invited by the Creator of the universe to join with Him as He shows His love to His creation.....His desire is that we allow the love of His Son to flow through us so that the lost and dying of this world might be saved.

What greater work than this would we want to participate in ?
