Faith in Christ saves us because it is through His finished work on the cross that we are pardoned from sin and receive life.
The assurance that faith in Christ saves is primarily derived from the truth of Scripture. John 3:18 states that whoever believes in Him is not condemned, indicating that faith in Jesus provides assurance of our salvation. This faith does not earn salvation; rather, it reveals the salvation that has already been granted through Christ's finished work. In Ephesians 2:8-9, we are reminded that we are saved by grace through faith, not by works, so that no one can boast. It is God who initiates salvation and gives us the faith to believe, asserting that our redemption is solely by His grace.
