All of us as children of God are called to bear fruit, so that the Lord will see that if we are doing things right and if we want to be with him for eternity.
Ephesians 5: 9 (because the fruit of the Spirit is in all goodness, justice and truth).
God asks us to show the world its wonders, and the best way to do it is for others to see our change and to realize that we begin to bear good fruit, a fruit that attracts others to the light that is Christ.
when we get to the ways of the Lord he cleanses and restores us, that is, if before we were bitter and offensive, after accepting the Lord, we must begin to be cheerful, respectful, humble and grateful.
We also have to start caring for our testimony, this is also a way to bear fruit and be blessed by God.
