Soteriology is the study of the doctrine of salvation. Soteriology discusses  how Christ’s death secures the salvation of those who believe. It helps us to  understand the doctrines of redemption, justification, sanctification,  propitiation, and the substitutionary atonement. Some common questions in  studying Soteriology are:

Once  saved always saved? Perhaps the most heart-wrenching fear some believers  live with is that we can do something to lose our salvation. But the Bible  speaks clearly about the eternality of our salvation and how we are preserved by  the One who bought us with His blood.

Is  salvation by faith alone, or by faith plus works? Am I saved just by  believing in Jesus, or do I have to believe in Jesus and do certain  things?

Is baptism required for  salvation? What is baptismal regeneration? Baptismal regeneration is the  belief that a person must be baptized in order to be saved. While baptism is an  important step of obedience for a Christian, the Bible is clear that baptism is  not a requirement for salvation.

What is  repentance and is it necessary for salvation? Biblical repentance is  changing your mind about Jesus Christ and turning to God in faith for salvation  (Acts 3:19). Turning from sin  is not the definition of repentance, but it is one of the results of genuine,  faith-based repentance towards the Lord Jesus Christ.

What  does it mean to be a born again Christian? The phrase “born again” literally  means “born from above.” It is an act of God whereby eternal life is imparted to  the person who believes—a spiritual transformation.

Other than  Christology, Soteriology is the area where Christianity is the most different  from the cults and other world religions. Understanding Biblical Soteriology  will help us to know why salvation is by grace alone (Ephesians 2:8-9),  through faith alone, in Jesus Christ alone. No other religion bases salvation on  faith alone. Soteriology helps us to see why. A clear understanding of our  salvation will provide a “peace that passes all understanding” (Philippians 4:7) because  we come to know that He who can never fail is the means by which we were saved  and the means by which we remain secure in our salvation. If we were responsible  to save ourselves and keep ourselves saved, we would fail. Thank God that is not  the case!

Titus 3:5-8 is a tremendous summary of Soteriology, “He saved us, not because of righteous  things we had done, but because of His mercy. He saved us through the washing of  rebirth and renewal by the Holy Spirit, whom He poured out on us generously  through Jesus Christ our Savior, so that, having been justified by His grace, we  might become heirs having the hope of eternal life.”
