Think of it, the Holy Spirit led Phillip away from a great revival that was taking place, to this one Ethiopian, an individual.
The individual souls are just as important as the multitudes to Christ. Personal work at the altar or witnessing in the street is just as important as revival in the church.
Our job is not to change a society or the culture, but the soul of the individual. Jesus Christ is Lord of all or not at all. He is Sovereign of all: He is King of kings, Prophet, Saviour, Redeemer, etc.
If an individual does not believe that, he cannot be saved, if he rejects Christ, he cannot go to Heaven, but will go to hell. You cannot deny Christ and go to Heaven. It matters not who you are.
Isaiah 8:20, “If they speak not according to this word, if is because there is no light in them.”
Phillip and the Apostles preached Christ; our message is Christ.
1 Corinthians 1:23, “.but we preach Christ crucified.”
2 Corinthians 4:5, “For we preach not ourselves, but Christ Jesus The Lord.”
John Bunyan was in jail for 13 years, why? Preaching Christ without approval; that is a license from the established church.
