The New Testament is very clear that God the Father requires every Christian to bring forth spiritual “fruit” (John 15:1-9) into His kingdom through “works of faith” (James 2:20-26).
The spiritual “fruit” being referred to represents the lost souls in this world — those who are living a life of sin (Luke 15:10). This is because Satan has ensnared them in unbelief (Heb 4:6). The only way to “save” them (Rom 10:14) is for God’s people to preach the True Gospel and to demonstrate their faith using the Gifts of the Spirit (Mark 16:20) that produce ‘works of faith‘, as stated in the scripture verse below.
“And this gospel of the kingdom shall be preached in all the world for a witness unto all nations [by My disciples in My churches]; and then shall the end come.” — Jesus speaking(Matt 24:14)
