The book of The Revelation is written to the servants of God. The patience and faith of the church is stated. The true servants of God will be sealed.
Did JESUS mean what He said? Why are so few going to be saved not being able to enter the strait gate? Obedience unto righteousness unto holiness is required to enter heaven.
The first step in restoring the faith that was once delivered to the true church is the truth that JESUS is the only true God.
