In Hebrews 10 we get the will of God (verse 7),
The work of Christ (verse 10),
The witness of the Holy Spirit (verse 17).
How simple is the gospel! God wants us to be saved, so Christ died to save us, and the Holy Spirit comes and tells us we are saved. The whole thing is of God. Man’s only part is to believe, and receive, and enjoy this wondrous outflow of divine love.
