There are not many ways of salvation—only one. That one way has been appointed by God, and is revealed in His Word. Man has many religions, many creeds; God has just one. This makes the question of how a sinner may be saved both simple and sure.
Since God has appointed the way of salvation, man has no voice in the matter. He has made known in His Word what that way is, and there is no room left for others.
God's salvation is in Christ alone. "Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved." Acts 4:1212Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved. (Acts 4:12).
"Salvation is of the Lord." Jonah 2:99But I will sacrifice unto thee with the voice of thanksgiving; I will pay that that I have vowed. Salvation is of the Lord. (Jonah 2:9). It is obtained through the atoning death of the Lord Jesus on the cross. Salvation thus procured is proclaimed in the gospel; it is "the gospel of your salvation" to every creature. There is salvation for all, without merit, without price.
"The way of salvation" is clear and plain. It is not left for each to choose his own way. It has not been given to "the church" to devise or appoint how sinners are to be made possessors of God's salvation.
He has caused it to be recorded in the Word, that all may know it, and He will never alter, never modify, never add to His plan.
