Salvation is:
By the will of God: Hebrews 10:7-10; also 2 Peter 3:9.
Through the work of Christ: Hebrews 10:10; Romans 5:8; 1 Corinthians 15:3.
By the witness of the Holy Ghost: Hebrews 10:15, 17.
How simple is the gospel of God's love and grace! God wants us to be saved. Christ died to save us. The Holy Ghost 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.
